You need to choose carefully whether the risk outweighs the benefits before you make your decision on whether you should do it. Because once it's done it is done. Just like when you decide to eat a bunch of chocolates you know that it's only one moment on your lips but a lifetime on your hips. You may be running late but you shouldn't risk getting a speeding ticket. Because if you do get pulled over the time it takes for them to write you a ticket will only make you arrive a lot later. Not to mention the unnecessary cost of the ticket. You are better off arriving a few minutes late.
