It is a pragmitic delay as the power delivery infrastructure has no hope of achieving the 2030 deadline. I'm not really convinced the 2035 one is achievable.
By 2030 most people who drive a small car because there is no viable public transport and don't actually enjoy driving will have an EV, leaving ICEs to people like us.
By 2035 I'll be 83 and probably not driving far, if at all. The Boxster will be my last car, I suspect. Talk about going out on a high....!
