What's weird is that Presidents aren't allowed to drive themselves. Secret service is no doubt impounding that new car until he's no longer their problem.
That's code for he never learned to drive. Whatever polite bullshit you're used to from other politicians isn't happening here, so you can safely assume the exact opposite of what he's saying.
He did have a drivers license and was shown driving in 2014 on a video that his wife posted. The license expired in 2020.
He probably didn't renew it, since ex-presidents are also not allowed to drive, so he hasn't been allowed to drive since 2016.
