Why can the pilot shut off the fuel during takeoff?

Fire, probably. But also, how complicated would you make the system if you needed to prevent certain switches from working during certain times of flight? At some point... we're all just in the hands of the people in the cockpit.

I can't put my car into reverse gear while driving down the freeway.

You also can't reverse a plane while flying it...

This is a rather odd comparison. You can slam the brakes, yank the steering week, and do all sorts of things to intentionally make the car crash.

You can put the reversers on for a tactical descent though :P

They look nice, but they can be turned on the C17 (and probably other military airplanes).

Commercial airplanes have safeguards against in-flight thrust reverser deployment. That is why they only work in tandem with the ground sensing systems - like the airplane must firmly believe both main landing gears to be physically on the ground for both reversers to be operational.
