Many people are currently using EVs. The shorter range isn't a problem for many and I imagine it's something one would be acutely aware of, which would explain why stranded EVs, with flat batteries isn't a common sight. Anyway, do we really need another EV vs ICE thread? This topic has been done to death several times. :horse: |O |

So we do not need a density of chargers to match the number of cars. What we do need is dedicated on-street parking bays with EV chargers, about 10-20% of all spaces on a given street should consist of these. --- End quote --- No. You'd need 30% to 40% of the parking spaces AND solve the problem that people don't occupy a charging point unnecessary. Are you going to wake up at 3:00 in the morning to move your car so the beighbours can charge theirs? The reality is that the current BEVs are not yet evolved to a point where they are real alternatives for cars that run on fuel or hydrogen. It takes another revolution in battery technology to increase the capacity / weight ratio and charge speed. The only charging infrastructure that makes sense financially due to resource sharing is to have superchargers like/at gas stations and charge there within a few minutes. Charging at home / in the street is a temporary crutch and will dissapear again after 10 to 20 years from now. --- End quote --- Don't know where you get 30-40%, even 20% would be on the high end. --- End quote --- That is what the Dutch government is aiming for: One charging point for every 2 to 3 cars. |

A bit off topic, I get a kick out of the endless naysayers regarding electric cars. If we focused on the problems during the “ Let’s go to the moon “ phase of development, we would have never made it off the launchpad. Meanwhile Tesla cars are everywhere (both of my neighbour's drive one), and Musk is the richest guy on the planet. I have a good chuckle every time I read one of these “it’s not possible, doomed for failure “ scenarios. |
