I was driving home from work last night and my car suddenly wouldn't accelerate anymore, like it would if it was set in neutral, but it was still in drive. Everything electrical was still on though. I pull over to the side of the interstate, turn the car off, and try to crank it back on, but the car won't start. I had a friend drive me back home, but the car is still there. I drive a 2008 Mazda 6.
