Why explode, the car didn't accelerate or interact with the continent

Even ignoring the tires interacting with the road, you have air molecules. I don't think that would be enough to destroy a continent, but it would be very destructive.

Wow, that seems to be the very first What If ever!

For the same reason this baseball causes an expanding plasma-ball disintegrating everything. Fusion with air molecules that can't get out of the way fast enough https://what-if.xkcd.com/1/
