Nope, 10's too much - that would slow the 'scale' acceleration down by 100, because it's metres per second squared.

Try this then: you know how you used to hear "my car does 25 mph, so that's a scale speed of 250 mph"? Yeah, right... have you ever heard of a (1:1) off-road race car doing that speed? Instead, try multiplying actual speeds by about 3.2 (square root of 10):

Buggy: 35 mph => 112 mph 'scale'. WRC cars go how fast?
Touring car: 45 mph(?) => 144 mph 'scale'. Sound about right?
Velodrome / oval racer: ~60mph => 192 mph. NASCAR?
'Insane Run' record: 100+ mph => 320 mph. Maybe that's still a bit fast... but if you put the 1000 hp Penske-Mercedes Indycar (or a Can-Am / Group C prototype) on the bowl at Nardo, how fast could it go?
