I have a relative who is an actual rocket scientist/genius. He says electric car manufacturers are dumb. He says they should standardize about 5 battery sizes for compacts to semis and have battery exchange stations where you pull in and your battery is swapped for a charged one in 5 minutes. No one would own batteries or ever have to buy a new one. No more hours of charging.
I’m with ya
Like gas tank exchanges.
What I detest is stores like Kohl’s using several spots up front where disabled should be. WTF!

My impression was Tesla is doing this.
Maybe it was never implemented?
OK - All modesty aside, I’m not “genius level”, but I’m pretty stinking good. I’m a common-sense Mechanical Engineer (that should be redundant, but often is not...) who’s been screaming what your relative has been saying for as many years as I can remember.
I had a professor who looked at an idea I had one time and said (paraphrased), “If your idea does something that’s already being done, but it’s more complicated and costs more, it’s a BAD idea.”
Funny I saw this thread today. Earlier in the day, a friend asked me as an engineer, what I thought of electrics. Here’s what I told him:
How many Jiffy Lubes are out there? Ready-made infrastructure! If you had a standardized battery pack or fuel cell unit that connected to your car’s undercarriage, you could pull over the pit, have them remove the dead battery(ies), and replace it with a charged one. You are gone in 20 minutes.
