And, well, a lot of people _can't_ have their own speed bubble.

Most of us, for quite a bit of our lives - when we're under 18 for a start, and over 75ish it isn't really a good idea (yes, I know, no viable alternatives for a lot of people right now, but it's still a bad idea). Whenever we've had a drink. There's a dozen or more medical conditions which can snatch your right to drive away with the stroke of a doctor's pen, and that's before we consider all the common meds which come with a don't drive advisory warning.

And then there's all the other times where it'd sure be nice not to have to. When we're tired, or stressed, or sick, or weather conditions make things dicey. Or when I just wanted to read that book, magazine, blog article, or watch that movie. Or we've got to be someplace with the kids but they actually need our undivided attention.

The point is, even if you drive and like driving, it's just basically civilised to have other affordable options. Even if they're a bit slower or come with other compromises, they should, y'know, exist. And sometimes allowing them to exist comes at a price of making driving your own speed-bubble at the times when you can and want to a little less convenient or more expensive.
