I was coming up to a red light the other day at a normal speed and breaking. All of a sudden my back tire starts sliding for the few feet left to the light. I hadden't noticed the big black oil spots on the ground. The worst places for liquid spills in town are at lights because the cars are just sitting there and leaking all over. Next time you pull up to a stop sign or light look at the ground and check it out. I wish the DOT could do something to enforce some kind of manditory check ups to keep all this from leaking onto our roads.
