First, I don't understand why you need to "stop on a dime" to avoid a stationary object ahead?

Second, a huge part of safely operating any vehicle in an environment (especially a chaotic one you share with cars, bikes, and pedestrians) is awareness of your surroundings and the ability to avoid collisions. This is seriously driving / biking 101.

If you are zooming around on your bike and just thinking "hope no objects / people / cars are sitting stationary in my way because there's no way I can stop and I'll definitely hit them", then you're a dangerous menace.
