Doesn't the hand-brake operate on the rear wheels? Unless in each case the hand-brake was not used, how could it be so easy for the tow truck to remove these cars?
You really stop and think about that question before posting it?
Normally I wouldn't bother giving you the time of day, but since someone else observed that my question was legitimate and I have a few minutes, I thought I'd do a quick google (I'm not an expert on car mechanics and don't profess, as you do, to know all).
The position, if one dares to assume that the wealth of knowledge available on Wikipedia is superior to your own, seems to be:
".........the stopping force provided by using the handbrake instead of or in addition to the footbrake is usually small and would not significantly aid in stopping the vehicle, again because it usually operates on the rear wheels which suffer reduced traction compared to the fronts while braking." (my emphasis).
On that basis, it is logical to assume that the handbrake would offer some resistance, at least initially, making towing more difficult - unless as Bitter suggests it is not being used at all in reliance on an automatic transmission locking mechanism.
You should really stop and think yourself before attempting to start another unnecessarily heated debate which will inevitably end in you running out of logical argument and resorting to profanity!
Having spent those few minutes looking at Wiki and addressing you, I've spent more of my day on you than you deserve. Accordingly, you will henceforth be ignored. Have a great day!!
