Today, this one was mine.
Drive in the rain with bad tires. Begin to slow down as you approach the lights. Realize your car is losing traction and you aren't slowing. Slam on the brakes in panic so the brakes lock up. Once the brakes lock up, you can now no longer steer your car. Watch in horror and panic as the rear bumper of the car in front of you approaches.
Thank God you are now only travelling 5km/h.
If you must do this, be sure to hit a very kind old man who will look at his rear bumper, declare there to be no damage, express his concern for your wellbeing, be generally very kind to you, and send you on your way after stating there to be no need to collect insurance information.
Get back in your car, cry a little, and pray that man has his kindness returned to him tenfold.
Be eternally grateful that both you and your small child are okay.
