Without taking a stance in here on what is "right", as this is a very personal decision, I will note that there are some real presumptions going on here that I just can't support.

1) that there's always a detour available down Leave It To Beaver Lane

2) that the whole point of any defense is to defend the bike, rather than your own skull / life

So make your own mind up based on your own situation, which includes a variety of personal risk management decisions and ethics. Just don't get all holier than thou on someone else, until you get their whole picture.
