If natural disasters strike, is it possible for you to bug out without getting stuck with thousands or hundreds of thousands other car users as well? Just asking, because a backup secondary route either on foot or smaller off-road vehicles (motorbikes or just regular bikes) might be prudent for planning. But yeah, many time-sensitive events are able to be easily solved with our own cars. There's a flexibility that is absent when relying on public transit and ride-sharing. Does it worth the trade-off of maintaining your own vehicle and it's attendant issues? In my opinion, it is. For some others, it isn't. It would be better if cars can become a non-essential for everyone in the world though, or at least the urbanites. Less traffic jams for the rest of us.
