because we have to do more tests ( like hazzard prevention) etc
if you seriously think a computer test that you can barely see any definition on makes you safer, you have no idea. its 1 extra test, which proves nothing but clicking, not actual braking and swerving etc.
before you say im some old whinger, im on red p's and did the test not too long ago, it was stupid, worse then playing need for speed 3, atleast you can swerve and brake in the game!
if its for work and you get an exemption there is no need to hide driving a v8. work purposes is fine, but you need the actual exemption and not just make up some story to the police. trying to hide the fact its a v8 makes it look shifty.
