Nice concept though, virtual wheel driven car, but probably no GPL

Some even have the insane opinion of double clutching on the up shift, and
shifting for motorcycles, LOL
to hear the throttle burp :)
Olav your answer can be found here;

For all the other knuckleheads that think I'm talking rubbish, I won't even
try to explain technically the reason why not to double clutch synchromesh
transmissions, as I'm sure you have no understanding of modern mechanical
transmissions at all.
I'll just refer the opinion of the Chief Instructor at the Porsche Driving
Experience and 10 time Endurance race winner Hurley Haywood.
"My assigned professional driver was Hurley Haywood, a long-time Porsche
team driver and winner of both LeMans and Daytona"
"The manual gear shifter was easy to shift but felt a bit floppy.
Double-clutching or heel-and-toeing are not needed to shift down into a
lower gear - "double-clutching is for truck drivers" said Hurley - the
six-speed's syncromesh operation is smooth enough to handle quick shifts and
sudden engine loads."

Daytona Beach - Winter Speed Carnival 1903 - 1935
1919 - Ralph DePalma Driving Champion and winner of hundreds of races, sets
new 1 mile record driving 905 cubic inch V-12 Packard on beach at 149.875
mph. DePalma also sets World Records for distances of 2 to 20 miles and
standing mile. His standing mile record of 92.713 mph is unbroken for 36
years.
The point of this is to match internal shaft speeds of the transmission.
Synchros on street cars do this automatically, but race engines often do not
have the feature as they are more complex maintain. Practicing this on the
street has the added benefit of extending the life of your synchros.
