comment What format should I select for automatic upload to Strava?
Downvote? Just curious. I've never understood how this site is managed. For me it's been by far the hardest of the SE sites to get any useful information out of.

comment Can you be ticketed for breaking the speed limit on a bike?
It depends. See for example "Teen cyclist fined for riding 37mph in Richmond Park".

comment How can I merge two GPX files into one?
@JamesBradbury: Simply cutting and pasting text proved to be by far the simplest approach. With a little detail (e.g, about locating 'trkpt' elements and pasting them into tracks) that would be an answer.

comment How can I merge two GPX files into one?
GPSBabel is a bit of overkill for simple merges. In fact, it has large but odd collection of capabilities. So far, it looks like simple text editing does the trick. GPX files are (it turns out; I didn't realize when I started) pretty simple XML files. Combining them is straightforward with a text editor.

comment How can I merge two GPX files into one?
@Angelo: What I have is a list of several times at various (approximate) milages, where I rode over a pad. That, and a GPX of the route (without any timings). I'd be happy if I could take that and create a "route" that had matching times for passing the locations of the pads, and simply averaged the "ride" segments in between over the course of the route.

comment How can I merge two GPX files into one?
@Angelo: Is there a way to make the process of creating a route for tie missing data less painful. What I have for that is (1) times at a few milestones and (2) the route. But it's not clear how to use that to create a "ride" without a lot of calculation and tedious work. There must be some way to take that information (even just a start, and end and a route) and create an "averaged" ride, but I can't find it.

@JamesBradbury: That's a good idea. Simple cut and paste in a text editor might do the trick. As Angelo says though, I'm finding the hard part (despite suggestions here) to be creating the missing route.

comment Edit gps recorded track
You mention combining tracks. How does one do that if one is not using a Garmin device?

comment What supplies do riders cary on century sportives and how do they carry it?
@jimirings: Agreed. We've got to stop this obsession with shutting down things that seem even remotely list-like. Somehow the other SEs have a lot less trouble with this.

comment What supplies do riders cary on century sportives and how do they carry it?
@Kibbee: I'll need to be prepared for several scenarios. On paper, there's water every 10 miles, and food every 20 or 30, but I can't rely on being able to eat the the food, so — at least until I know more for sure — assume its for the whole ride.

comment Can I attach a trailer to a Bixi bicycle?
@freiheit: Looking more closely, it seems (I haven't tried, but I assume) that the seats can't be completly removed from Bixi bikes, so the question may be: (1) are there standard seat post attachments for trail-a-bikes that clamp on (rather than requiring removal of the post) and (2) is attaching a trailer to a Hubway/Barclays/citi-bike allowed?

comment How do the pricing structures of various bike sharing schemes compare?
I was thinking that a thorough answer to the question asked by my town government in their consideration of participating in the extension of a a nearby bike sharing scheme was "practical".

Really? That's not a serious guess (or a very helpful one).

comment How do the pricing structures of various bike sharing schemes compare?
Good link, but there are some bugs in the first two figures: they don't take the base plan cost into account, and the stack values that they mean to compare. I've gone and worked out some examples for a few plans.

comment Is it generally the case that bikes are allowed to use the “full lane”?
That's a particularly good statute in terms of the rights it gives cyclists, but like many it asks too much of drivers: can they really judge when my safety "warrants it"?

comment Is it generally the case that bikes are allowed to use the “full lane”?
That's the crux of the question. There seems to be some confusion among bloggers, etc. about an important distinction between the general idea of "riding like a car", and the idea of taking the "full lane". While the former seems widely legal, the latter is often explicitly not.

comment What statutes govern the directing of traffic by citizens in Massachusetts?
Interesting. I hadn't been looking at it from the driver's perspective. But you're right. I expect that though a driver might make the case that he was signaled to proceed, it was really his responsibility not to.

comment Can cyclists legally ride on the sidewalk?
Whether it is more dangerous or not depends quite a bit on local conditions. There are many stretches of road without driveway or other crossings, with rarely used and well-paved stretches of sidewalk. And there are many stretches of road with extremely irregular pavement, drains, debris, and fast moving heavy traffic. Where these conditions coincide it is certainly safer to ride in the sidewalk. (And in the specific locales I'm thinking of, it is also legal.)
