I keep seeing articles like this LA buses 3/4 million dollar vehicles that dont/cant work.
Other articles showing that in hilly areas, the brakes dont work in part from attempts to capture energy stopping function, other cities having problems too, Minnesota
To invest big bucks into one as a personal vehicle , without the ability like these cities to bring back a retired Diesel to handle operation while the electrics are being continually repaired just seems crazy for all but the insanely wealthy.

EV delivery trucks were common about 100 years ago. They worked fine then so we just need to reinvent the wheel and other parts.

Yes you can find some issues if you go looking for them. You can find even more boring success stories too but they don't make for exciting print.

Busses in both stories appear to be from same company. It started up in 2017. Sounds like they got in over their heads.

This sounds like an issue with logistics (ie: getting parts).

For low speed limited range local use where it can go back to a yard and charge overnight, electric is great. That fits in well with local delivery (fed ex) or city busses.

For RVs where most people get out on the freeway and do a few hours of driving then staying someplace with limited electric, we are a lot further away.

There is an interesting article in the recent Car and Driver magazine where they had a thousand mile race with 9 electric cars. The speed limit was mandated so the winner would be determined by charging efficiency and network availability. Some vehicles spent half as much time charging as they did driving and that didn't even include overnight charging which was not counted.

It is coming though. Mercedes just announced they plan to transition to full electric production by 2025 which is a little over 3 years away. Don't know if it includes their big rig models but the article said it included all model lines. Doubtful if the European or domestic infrastructure will be ready by then.

One thing I'm not sure of for police use is idle time sitting on the roadside running heat or AC. Either watching traffic, surveillance, or completing paperwork there is a lot of time spent in the vehicle, if the car is driven maybe 50% of the shift, and just sitting with the climate control running, will a single charge cover a full shift?

This is so different from gasoline it is hard to get a handle on it. The climate control uses very little power when you are not idling a 400 hp gas engine to drive 5 hp of accessories. I believe it stated they run two shifts between charges and a depleted battery has never been an issue.

I assume there will be a dramatic increase in the electric grid capacity to handle all this new stuff. Some Hydroelectric generating dams in the west may soon be out of water. Just musing
