find empty road; from a stop or nearly stopped, press accelerator to the floor; don't hit anything, stay on the road and lift off the accelerator anywhere between 60-100 mph (if you are scared and above 100 you over did it a little)
repeat 2 more times as quickly as reasonable
IF you feel sick, you have the AWD; IF you just can't hardly stop smiling you just have the RWD
If you don't want to risk a ticket do what hanergy instructs above - just less fun.
(if you let the cop test drive - he'll probably thank you and perhaps give you a warning, right?)
