so, we switch to battery electric vehicles, charged via already fragile power grids, powered by renewables known for their constant stable output. and the cars get remote kill switches too.

@cnx here in germany one can rather easily go shopping by bike, even in most rural areas. the problem is that society has put up so many expectations and is so hyperindividualized that it often just isn't practical. people often work someplace not in bike range, if you have kids stuff gets even harder. it really takes up much energy to swim against this stream, and many don't have it because of the daily grind.
