Converting one car to an EV (and accepting the resulting compromises) is more realistically in that spirit than something like “knock down your house and build a mid-rise on your lot” would be.

Collective action and sacrifice will be necessary to change density. Still that doesn't prevent us from adapting to more sustainable transportation modes, both collectively and personally.

I was addressing the fear that governments have of disrupting current mobility 'standards'.
