Seems moot now. The 407 toll road around Toronto has no toll booths at all. If you drive on it frequently, you can get a transponder but otherwise, they take a picture of your plates, look you up, and mail you a bill. This does work -- I've gotten a bill for my NY car after a trip. The web site at http://www.407etr.com/ makes it clear that the transponder is completely optional, and won't save you any money unless you use it more than 7 times a year. (The transponder costs $2/mo and saves $3.45 per trip.) The easiest way to get a transponder appears to be to drive on the road, wait until you get a bill on which they will have assigned you an account number, then use that number to log into their web site and order one. An article in Wikipedia says that congestion tolls in London (UK) are also collected automatically by taking pictures of license plates.
