Your only 16, which as far as i know means you cant drive. It is difficult, ask anyone, I dont think anyone out there has never sped in their car. And no, because going 5mph, you normally still get raped by cameras etc. cops themselves may let you off, but they wont if your doing say 10mph over, its not slowly increasing, its getting worse and worse. I dont disagree with speed limits, in built up areas etc, but some limits are rediculous, and in certain areas IMO it is acceptable to break the speed limit, providing you stay at a speed where you are comfortable and dont push it too much. Use speed where safe etc.
