Riding fixed gear is like driving without brake lights

Ha - so I just asked my mother, who has driven for 45 years:

Q: Someone on the forum has suggested fixed gear riders are more likely to be rear-ended by other vehicles since our legs are always spinning, unlike freewheel riders, and we have no brake lights...Do you agree? Would you notice that as a driver?

A: No

Is she tired after driving for 45 years?
