Good thread and interesting replies. Talking car here first, best one I have driven to date, is the BMW i3. Some clever tech in this small vehicle with suicide rear doors. It is rare to have to use vehicle brakes, you just remove foot from pedal, vehicle reduces speed rapidly, while this is all going on, you view the power gauge, to the right, mileage range, to the left, show energy from slowing process going back to batteries. I've seen me going down a steep hill with say hundred mile charge, to reach bottom of hill with say, hundred and three mile charge.
On the other side of the coin, last month I attended an event at near Edinburgh airport, I was using Nissan small eVan, which is three seater in cab only. Fully charged @ hundred mile range on readout. BTW, trip distance, thirty two mile round trip. Dark and cold on return home, got caught in traffic on Edinburgh shitty bypass, crawling along, it really was horrendous viewing the miles fall away, it got so bad, I turned heating off, was close to hyperthermia when I got home. I then had to drive to nearest charging post, which is fifteen min walk from house, hour and a half on quick charge was suffice to return to Royal highland centre Ingliston, which does NOT have a charging point, which is shocking.
While the eCar has come some way, it will get better, that I am sure of. Be interesting to see how this develops further towards heavier goods vehicles and motorhomes. But you do have to box clever when dark and cold hits you, the miles drop off.
Lots of clever R&D ongoing regarding picking up power while driving, like a tram, except power pickup point is built into road.
