Security cameras have a standard called "pixels per foot" (ppf). This means that at a certain distance, an object 1 foot across (about the size of a US license plate) will have a certain number of pixels. As the object moves further away, the number of pixels per foot decreases. As the object moves closer, the number of pixels per foot increases. This is ...

Following the advice of those who commented: I came upon this solution. Cut the access length (about 1 cm), leaving enough for adjustment Melt the ends of the straps with a torch Use electrical tape to wrap the ends tightly so they resemble 'method 1' but without the excess length.

As some have pointed out in the comments, the question is somewhat misleading, i.e. speed difference is always going to be greater in a head on collision, all things being equal, versus if the collision had been a rear ended collision or a t-bone, but, as @Daniel notes: "This is (mostly) unrelated to the probability of the collision in the first place" ...

If the area doesn't look very "lively", sometimes I just leave my rig outside a shop. My little trick though is I put my bike into some nasty gear, like either the fastest one or smallest/smallest ring combo, so the chain hangs loose.

A cable lock is going to be more like 0.5 lbs, but not as strong. But, for a quick in and out it that may be the best trade off. The weight of the bike plus the weight of the lock to protect the bike is ...

I've seen three bicycles with what appear to be stress fractures at the bottom of the seat tube and top of the bottom bracket shell. A bike nut friend with more metallurgical knowledge than me tells me that this is caused by work hardening -- which is the same thing that causes a paper clip to become brittle after repeated flexing. Now that this has ...

Buy a very loud alarm and, if the person ahead is wearing headphones, blip it as you approach. Note : such items can be purchased at Maplin stores in the UK http://www.maplin.co.uk/ EDIT in response to Andy's feedback. The original question is essentially flawed. It seems to ask "How can I attract someone's attention when they can't see, feel or hear ...

this is a question I've given a great deal of thought and experimentation to, after an accidental discovery some years ago. Long story short: cycle where the kerb-side wheel of a car or truck would be, and magically, Jedi-mind-trickily, almost ALL drivers give you plenty of room when passing, wait patiently to pass, and are not in the slightest bit annoyed. ...
