Setting up your wife's car so that it can throw out 2 foot of flame from the exhaust after hard revving the engine, may look cool and be great for targeting tossers who sit to close behind you...... May also draw the attention of the constabulary.
Same car another story
Running late for commodore sitting up my freckle, kick it back a cog blast of commodore couldn't keep up slow down for traffic commodore back again, repeat... repeat for 5km.
Arm comes out of the commodore pops a spinner on the roof... oh smeg
When the nice policeman states the obvious that you may going a bit quick and he couldn't keep up, when he estimates that you were traveling at 20km less than your last gear change, apologize, put a sheepish look on your face, take the ticket and be thankful, I was.
Same car yet another.
Do not drive a warm rotary engined car with a light flywheel on pea gravel unless you like excitement.
It was a fun car
