Kevin Hart‘s scary car wreck has Dr. Phil shook because, like Kevin, he owns a classic car … and he’s now realizing it comes with some serious safety concerns.

The Doc tells “TMZ Live” his ’57 Chevy is the same as Hart’s 1970 Plymouth Barracuda in that it’s equipped with lap belts but not safety harnesses … and he doesn’t know what to do about it.

As Dr. Phil says — they don’t make cars today like they used to … and that’s not always a good thing. He shows us there’s really no way to easily install shoulder strap seat belts with the way the car’s built. That’s not the case with Kevin’s Barracuda — shoulder straps could have been installed.

Phil points out old cars like his and Kevin’s don’t perform nearly as well in crash tests as modern vehicles and, without making changes … survival rates in crashes are much lower. In fact, he says he’s stunned Hart is still alive.
