The problem with sustainable fuels is that they also cost a lot of resources. Those resources can come from farm land that could be put to better use instead. The energy required to create these alternative fuels also has to come from somewhere, which usually isn't mostly renewable either.

Furthermore the biofuels and efuels may be better for CO2 emissions, but still dump a lot of pollution in the air.

Until people start to rely less on their cars, the uptick of EV's will lessen fossil fuel usage. For many people car sharing would also be a good option for when they need a car. That cuts down on resource usage.

The best EV's in my opinion are human/electric hybrids, aka electric bicycles. They help people choose a bicycle over another motorized form of transportation, because it's often just a convenient and cheap option that gets you from where you are to where you want to go, when you want to go there... Something public transport isn't very good at outside cities, unless combined with (e)bikes or scooters for example for the last miles.
