Absolutely. Actually, I'm pretty well convinced that a big part of the problem is the thing that many drivers don't do: focus their attention on driving, which, as you say, is inherently dangerous.
I was a training ride leader for the Boston->New York AIDS Ride back in the mid-1990s, and I wrote this as part of a safety introduction for novice cyclists:
The best safety rule is this: don't crash. The best way to avoid crashing is to focus 100 percent of your attention 100 percent of the time on riding safely. If you are thinking about the cute guy or girl that you saw at lunch, or a problem at work, or otherwise watching a movie inside your head, sooner or later you will encounter a dangerous situation, and will get acquainted, up close and personal, with the pavement.
Change 'riding' to 'driving' and I think it still works pretty well.
It's really not that surprising. If Firefox has cleaned up its act, then Chrome would tend to be at least a bit higher because of its "process per tab" design. Similarly, IE is likely to show lower usage, because parts of it are probably counted as part of the Windows OS.
They perhaps should have copyright protection (as, for example, GPL software does), but should have to be distributed under a suitable "copyleft" license.
Just looking at the demos, it seems that identifying the characters might be easier for these, in one sense: they're moving.
Someone should explain to this idiot that, if a competitive market is delivering a good service, then the private sector will do just fine without having some potential competitors excluded.
I wrote a longer blog post on this back in 2009: http://richg74.wordpress.com/2009/07/03/gas-v-mileage-tax/
