I have owned no less than five vehicles that have less range in the gas tank than my Model 3 Tesla has in it’s pack which is 360 miles. My 1979 K5 blazer has well under 250 miles to the tank. 1985 Jeep Cherokee 260 ish, My 91 Rx7 had under 300. My 93 S10 also well under 300 miles to a tank. 97 Explorer was 270 a tank. 2003 F150 was just at 300 miles. Only my imports went 400+ miles the SAAB and both my Volvos both were the first vehicles I have ever owned that would do 400+
The important thing is not max range as these vehicles demonstrate its how rapidly and conveniently you refill that range. The trucks took 10 min or so to put 25 gallons in the cars were 15 to 18gal.
Tesla has solved this issue for its EVs the Model 3 will take a 250kw rate you can add 4.4kWh per min over the SOC range of 10% to 70% it slows down to balance the cells above 70%. Not quite but close it starts off at 100kw then ramps up once the BMS makes sure all the cells are in temp range then it rapidly goes up to 250 and holds it there till 70% and starts to ramp down as it starts to balance cells nearing 80% cut off. I can add 250 miles in 25 min on average at a V3 supercharger.
Since nearly no one drives more than 300 miles in a day on a regular basis, L2 home or condo charging is a better option you just get home take 30 seconds to pop the door and plug the plug then go zzzzzz. Yes people drive far on average twice per year farther than 400 miles from home. In reality for those two edge cases which is what they are edge cases you can rent a hybrid car if you only had an EV with 300 miles range and no supercharger along the way.
What’s your range in the winter when it’s 20 degrees outside, blinding snow storm and traffic slowed to 30 MPH and you’re towing a trailer with 2 snowmobiles for 280 miles?
