First of all, no one gets car sick while driving - already a major difference to VR. Secondly, most people who can get car sick can avoid it by sitting in the front row and looking only straight ahead.

Finally, even for people who get hopelessly car sick as passengers no matter what they do, the advantage of a fast safe private ride often outweighs the discomfort - especially since no one is spending more than 1h in a car more often than a few times a year. It is very hard to imagine what application could make VR give even close to the amount of utility that cars give you.

I'd bet those people only use cars when needed. Nobody will go cruising on a puke machine.

And we never need Oculus for anything. That's a big difference.

*for you.

for most people, I'd posit.

Very few people need oculus/VR, while a lot people need cars. Possibly a lot more like 10000x

honestly i want to know, what need is there for it? Why should i wear something on my head? what advantage does it have on computers/ handheld devices? what can i do on a VR headset that I can't already do on a computer or handheld device?

Sounds like a difference in kind.
