I agree with you on your other opinions, but disagree with you on this one.
It is true that we may be driving 100 miles without being aware of it.
But we must remember that this is on the condition that there is no time limit and that we can use any car we want.
This challenge has a time limit of one week and forces you to use a 1930's Bentley, a niche car with performance issues.
To add to that, due to a bug in the playlist we must finish all the weekly challenges in one play.
So in other words, we need to play for at least about an hour for this weekly challenge, including the other challenges in one play.
I don't think this is going to be fun.
