Electric cars are good if you actually need a car, but we currently use cars in far more situations than really need them. Shifting away from cars where they aren't needed will be far more effective than replacing gas cars with electric.
I don't see why those are mutually exclusive. Replacing ICE cars with electric and using other forms of transportation when it is appropriate both are important. I actually think the rise in electric personal transportation (bikes, scooters and weird balancing contraptions etc) could be a bigger game changer than electric cars especially within cities.
