This is not to cast any aspersions on the game - popularity is not everything - but things like MFS are perfect examples that even the best simulators are just niche products, not the future of the web.
Virtual reality can have all sorts of landscapes, and moving along a surface, whether it be hilly or flat like Tron, will be popular. Driving is one way to move along a surface, but there's also running, swimming, base jumping, skiing, snowboarding, skating, and others. I'm sure all will be common in the metaverse.
For an example of something where driving is exciting and totally unnecessary, see Rocket League.

It moves to almost boring territory, luckily I am not a type of person who tends to fall asleep behind the wheel (unlike my wife).
Suffice it to say that plenty of people genuinely love driving, both in video games and in the real world.
Flying won't make driving obsolete any more than mountain biking has made hiking and trail running obsolete in places that are accessible to mountain bikes.
