I have no idea what is wrong
 

It's a problem I've had like 3-4 times now. And I've never once even heard of this. I'll shift into reverse or drive after I turn the car on. And then when I go to give it gas, nothing happens. And when I try and press on the brakes, I can't. It's like they have like 4 cemebt blocks under it, I can't press it. Then I'll try and get it into park again, turn it on. And then it works just fine. What's this from??
