>Can someone smarter than me enlighten me when you would consider disabling bounds checking for performance?

Because it is faster. Worst case you are triggering a branch miss, which is quite expensive.

>It's like talking about how much faster a car would go if it didn't have to carry the extra weight of brakes.

So? Every wasted CPU cycle costs money and energy. Especially for very high performance applications these costs can be very high. Not every car needs brakes, if it doesn't need to stop by itself and crashing hurts nobody they are just waste.
