Which is fine if you live somewhere with either an existing public transport system, or the potential to create one.
Neither do a lot of other people.
And even when I did, much depends on your definition of 'efficient'.
Some years ago I lived in Sheffield, which has one of the better integrated tansport networks in the UK, outside of London, but to get from where I lived (my employer's choice, not mine) to where I worked took me two hours on public transport - each way. The same journey in a car took me an hour and the same journey on my motorbike took me 30 minutes, so you can guess which option I chose - four hours of my day taken up by traveling vs 1 hour of my day taken up by traveling? No contest. Besides, I'd far rather be on my bike than stuck in a crowded bus or train with a bunch of strangers.
As for 'war wagons', I've had a few 4x4s in my time (including a Landrover Discovery when we lived in Sheffield) and as it happens, later this week I'm going to look at another (Toyota Rav4) to replace my 20 yr old MPV (Toyota Previa). The Rav4 does twice the 'gas mileage' of my current vehicle, but it's not just that and my preference for 4x4s that guides my potential purchase. As you might have guessed from my opening comments, I now live in an isolated, rural area where public transport is negligible, there are a lot of places I go to that are not serviced by tarmac roads and the winters can be pretty grim, so a 4x4 is a sensible option for us.
Here in the UK, we get pretty pissed off at politicians pasing laws with national application from their rarified position as a 'metropolitan elite', so RA's suggestion might be valid in some grim, urbanised Socialist dystopia, but it doesn't work in real life.
