Often the voters that push for more spending are the people who pay little taxes, while the voters who oppose more spending are the people who pay lots of taxes.

But hey, when did a voter ever dislike paying for something with OPM?
Well, I do think that the way most Europeans live is a lot more localized and with smaller distances to be traveled on a daily basis.

But at the same time, most American life is pretty damn localized and there aren't long distances to be traveled on a daily basis. 80% of the US population live in urban areas (which I assume includes suburban and possibly even exurban).

But usually the issue is that a car is a very major purchase, and we tend to make those purchases partially on "what do I do 95% of the time?" but also "what do I need to be CAPABLE of doing the other 5% of the time?"

I think for most potential EV purchasers, they are scared an EV won't work for that 10%. Whether that's a road trip, or whether that's towing, or whether that's range anxiety in the coldest 2 weeks of winter.

It's why a lot of multi-car EV families have one BEV and one ICEV. The BEV is great for around-town stuff, and maybe could even be the majority of the family's miles driven. But they like to keep the ICEV (whether it's a truck, or used for road trips, etc) for the times when the BEV might be inconvenient.

In our family, EVs hadn't been mature enough yet when my wife got her RX350, but with our current lifestyle, a BEV makes perfect sense for her. She does the majority of her driving to/from work and running errands and would basically never have any problem with range. With home charging she'd never have to visit a gas station again. And then with me having the Ford Flex (and the Jeep), we'd have an ICEV with plenty of seating that could handle any time we need to take the kids somewhere, or any time we need to road trip. Since I primarily WFH with limited days in the office, our total familial gas consumption would DRASTICALLY drop if she was driving a BEV. When it comes time to replace her RX, it might be with an RZ. Granted that's probably 5+ years from now.
My wife bought her Chevy Bolt and this is exactly the situation we are in.  She uses the Bolt for day-to-day driving around town for errands and we use a ICE for longer trips.
We live in the Columbus, OH area.  We have had a few day trips where we have traveled to Cincinatti, Dayton, and Cleveland that we have used the Bolt for.  It's worked pretty well where we drive down, plug in to a charger for about 5 hours (a lvl 2) and then drove home.  We've driven to Indy and back once, and that required a hour stop in Dayton at a lvl 3 charger.  That is about the farthest we're willing to travel in it (at least in the winter months).

I think it is going to just come down to the technology catching up to where those charge stations can get down to 30 minutes instead of an hour.  Once the inconvenience of spending significant time charging goes away, the popularity of EV's is going to increase.

If I had one, I'd probably use it around town of course and for shorter trips of 3 hours or less.  My step son drove a rented Tesla from here to Cincy and said it went fine.  But I agree about making the charging times faster.  They are getting there, but I don't know how much faster they can go.

It could be ideal to have one ICE and one EV for many families.

There are pure physical limitations to charging time and storage capacity per unit size that we're not going to break through, unless/until some truly revolutionary battery/storage technology emerges as viable within the market.

Who has all the raw materials for these batteries? 

My limited understanding is that the US has an untapped reserve, but we're not going to go find it. Is this true?

We're currently planning our boy scout troop summer camp trip, we'll be driving out to New Mexico from Austin.  We'll have four vehicles carrying the kids, adult leaders, and towing the troop's equipment trailer.  But one of the dads/adult leaders who has two sons going, only has electric vehicles in his family.  He was asking that we stop twice on the first day, once for an hour, and once for an hour and a half, based on his EV's capability and the availability of charging stations along the route.

I politely suggested that he leave 2-3 hours earlier than us, so that he can arrive at the same time we do.

Charging rate (as we discussed early in this thread) is non-linear, with charging being faster when the batteries have less charge and slowing as you approach 100%. We think in terms of gas tanks where there'd never be a reason to stop before it's "full", but that won't be the paradigm IMHO when road tripping with an EV. 

Charging rate is also dependent on the type of charger. A Level 2 charger (that you might put in your garage for overnight charging) is WAY too slow for road trip use. But a 250 kW or 350 kW (current max) charger will add charge MUCH faster. 

What I think that Tesla has shown is that with planned charging and Superchargers, you might go from 10% to 80% in 20-30 minutes which is plenty to get you a few hundred miles of range. A few hundred miles gets you to the next charging station where you may want to get out and take care of food and/or bio breaks anyway.

Depends on which materials you are looking for. Apparently lithium is plentiful. Although I don't know how much actual mining capacity we have worldwide to meet a major spike in lithium demand. It doesn't matter how much there is if we don't have an industry that's sized to dig it out of the ground at the rates we need. 

The bigger issue is some of the other metals like cobalt and nickel. That's why automakers are trying to work with the LFP (lithium iron phosphate) chemistry to take some of those more rare metals out of the product, but unfortunately it's currently at lower storage density relative to lithium ion, but at lower price too. 

The industry is searching for a way to recycle batteries, but it remains to be seen if that can be done effectively and economically.

A few hundred miles gets you to the next charging station where you may want to get out and take care of food and/or bio breaks anyway.

But even a 20-minute stop to charge, requires changing a paradigm for many users-- and that's something they're unwilling to do.

There are many use cases of course, but for me the "fast stops" on my roadtrips are exactly the 5 minutes it takes to gas-n-go.  The "long stops" on my trip are the 30 minutes it takes to gas up the car, cycle the kids through the bathroom, grab some food to eat in the car, and hit the accelerator.  In no circumstances do my "long stops" on a family roadtrip, involve dining in a leisurely way that would take 45 minutes or more.

Not every trip we take is a long-haul roadtrip, of course.  If we're only going somewhere 2-3 hours away, I consider that a Sunday drive, and stopping off for a leisurely lunch would not only enable time to charge, but also enjoy spending time at a (hopefully) pleasant destination point.  In those cases, an EV would fit the needs.

what is needed is either longer battery life or a much smaller battery so you could have a 2nd battery for double distance

I'm the same way. An EV road trip would be a change for me. 

But remember, you get a benefit for that paradigm change. The other paradigm change for most EV owners is that you NEVER have to fill up your car with gas again. You charge at home in your garage overnight, and never have to go out of your way to visit a filling station. 

Would you make your rare and uncommon long-haul road trip a little more inconvenient to make 98% of your life more convenient? 

I look at it like the decision to have a mountain cabin, a boat, or an RV. It's the type of thing that if you're using it constantly, it's worth it. If you're not using in nearly every damn weekend, it's better to rent. In this case it's the opposite. If you're constantly towing, or going on long-distance camping trips every weekend, or road trips twice a month, maybe an EV is not for you. If you're going on long-range road trips once a year? It might be worth it to just deal with the charging, or rent an ICEV for the road trip. Because you make your daily routine more convenient by having your "tank" full every morning when you wake up.

But... I don't find 3-5 minute fill-ups every week or two to be inconvenient.  Do others really chafe at this?

It's possible I'm the exception, but that characterization really sounds more like a solution in search of a problem to me.

I usually plan on stopping about every three hours when doing a long trip.  I drove back from south Florida after baseball, it's about 8 hours, we stopped twice, had lunch once (fast food) and refueled.  I guess in an EV with a 300 mile range were I topped off, I'd stop after 240 miles or so and charge back to 80%.  That might take 20 minutes?

I could make it home from there.   Other factors include cold weather and that EVs don't make great range at constant higher speeds.  Forget towing of course.  This scenario is one where fast chargers are readily available, right now they aren't so much.
