Your lucky that you only got it on your foot, I had an old sport bike with a coolant resevoir under the rear seat. Well it stated leaking one day when I was sitting at a stop sign waiting to turn out on to a main road, I had no idea it was leaking until I took off taking a right turn, twisted the throttle as I was slightly leaned over and it was like hitting ice, I was on my side before I new what happened. It wasn't till I saw the coolant on my back tire that I knew why I went down. Luckily there wasn't much traffic at the time and needless to say now I am always much more cautious leaving intersections. 17 years on the street and that was my first time down, it kinda wakes you up to how fast things can go wrong.
