This is a car that uses flywheels to store energy. To charge the car, the charging stations spin up the flywheels, and then that energy is used to propel the car forward. Controls are:
"b" is parking brake (toggled)
"c" to charge the car
Up to go forward (away from last used charge station)
Down to brake/back up (towards last used charge station)
To charge, drive into the charge station and then press enter to lock the car in place, then hold the shift key to charge the car. Once the charge indicator gets to green, press enter again and go.

Idea for tachometer came from Killinich.

Updated so that the flywheels can now handle 1000 rpm (instead of 700), and they charge up much faster.

Now updated to include changes requested by s_noonan. There is now a parking brake indicator, and now the controls for the parking brake is "b", and to charge is "c". As far as not being able to slow down before the charge station, I moved the first station farther away from the hill which should help some.
