I have the occasional beer I’m on year two of LSV [low speed vehicle] 25mph max, 30 mile range. The GEM does what I need it to do. Old & retired, so my requirements are minimal, maybe 100 miles a month. I heard lots of opinion that the low speed would invoke road rage. I find that driving the GEM is much like towing a RV, if there are more than a couple of cars, I pull over & let them pass. Mechanically & electrically basic. Everything is smaller & lighter, so I can do the minor maintenance. The difference in travel time is minimal. Easier to drive safely as my physical skills decline.
Not really a climate solution, more of a pragmatic conservation of my personal resources.
A good start would be greatly restricting the speed, power & performance of vehicles allowed to be registered on the street. Wanna drive 0-60 in 3 seconds & three times the speed limit, go to the race track
