Sure thing! But there is not the need for every person to own a 1to steel case to go anywhere. Cars need a lot more infrastructure than an integral system, where you are able to use and change between bus/train/bike/walk/e-scooters - and so on - to reach your target.

I need very little infrastructure to get around on my bike. I can ride on dirt tracks or grass, I can carry it up and down steps, I can weave through alleys or traffic jams. It needs no fuel and I mostly maintain it myself. Car centric cities often have no meaningful bike infrastructure and yet cycling is still viable. It is the cheapest, most free, most egalitarian mode of transport.

Is is pleasant without infrastructure? Is it safe? No, dedicated cycle lanes are very important.
