This post is going to be of interest to UKers only, most likely.
I just got an email from a friend of mine, fledge, giving a link to a petition hosted on the website of 10 Downing Street against a new proposed scheme related to road pricing. It sounds innocent enough until you consider that on this proposed scheme, all UK vehicles would be tracked and movements recorded.
Normally I would call this a hoax, as emails like this are normally fakes. Sadly, however, this one really is legit. I'd never heard of this scheme before now and I'm guessing others haven't either.
The petition is at http://petitions.pm.gov.uk/traveltax/ for those who want to sign. You need to be a UK citizen to do so.
Also, see this blog post from Bruce Schneier for some more interesting thoughts from last December. [edit: Um, oops, that was from December 2005. I guess it probably doesn't have anything to do with it. Sorry for the confusion.]
