:)  At the risk of setting you off again.......

The motor is not just used for driving the wheels.
You will need a good battery to power the sensors and the computers.
And to operate the steering and brakes.

To get faster times you probably need better tyres for cornering grip.
And a bit of streamlining cover as air resistance quickly builds up
above 50 mph.
Maybe a wing for cornering downforce?

Then you need a stronger frame to carry all that gear.
