You could also say that having large batteries is a solution looking for a problem. If 95% of your driving is under 50 miles a day, then you are lugging around 150 miles worth of extra batteries (to get that 200 mile range) that still need a long charge cycle, where you could easily replace that 150 miles of batteries with an ICE that will get you unlimited miles with a 5-minute fuling stop in between. And still end up saving you on gas during 95% of your other driving.
- matthewdgreen 8y agoMost people drive more than X miles on Y% of their trips. For any given (X, Y) where Y is non-trivial — and 5% is non-trivial for most people — you can augment an X-mile battery limit by adding public charging stations. However the smaller X is, the more numerous and densely spaced those stations will have to be, which is deeply challenging given the layout of roads, and the cost of building charging stations. (This leaves aside the relative annoyance of making many brief stops vs. occasional longer stops.) Manufacturers like Tesla control both “X” and the charging station layout, and have limited influence over “Y” except insofar as it affects their ability to sell cars. Presumably they’ve crunched the numbers and concluded that they can’t support a reasonable customer base on small values like X=50.
