Perhaps people would "love" that but I have a feeling that the continued retreat from all forms of socialization due to technology is not a good thing by and large for society. I would guess that most people who think they desire this wouldn't even think they desire it in terms of safety but instead in terms of avoiding distraction or awkwardness.
Technology lets me socialize an order of magnitude more than I'd otherwise. We as a species have never been more connected. If it also gives me respite from having to engage with someone I'd rather not in a car, all the better.
Honestly, we could all use a bit more of a break from each other, in my opinion.
Point well taken, I meant physical / proximal socialization. I would contend that most forms of socialization over the internet are lower quality than a candid conversation with a stranger in a car ride.
