'...cannot ride a car' sounds like he's going to be riding on top of the car. Perhaps it should be '... cannot drive a car' or 'the man who can't ride in the car is sad' sounds more natural, but isn't accepted
Yep I did. Just putting it here because when flagging, there isn't any way to provide extra information or a description of why you think its wrong
Drive is a different verb, so that wouldn't be correct.
Ride in a car is fine. Flag it. It may take a while to correct though because the mods are working on clearing the flags from the bottom up.
