As Kryptonite struggles to respond to a whirlwind of bad publicity about their Bic pen-vulnerable U-locks, things are buzzing at a bicycle security discussion group I established a week ago.

You can now rent a Segway in Oakland, California. The prices aren't cheap.

If you own a Kryptonite U-lock for your bicycle, listen up. The Internet is buzzing with the news that it can be opened with a Bic pen. I've seen convincing video. Kryptonite's Web site doesn't acknowledge the problem, but this AP story says Kryptonite is accelerating the development of a new, pen-resistant lock. No mention of any refunds to customers. Can Kryptonite be held liable? Meanwhile, guard your bikes and get new locks. What a tragedy for everyday bicycle transportation use.

And then Giuseppe Cannella invented the jet-powered wheelchair in 2004, and sidewalks were never entirely safe again.

Earlier this summer at a technology conference, I heard about an innovative program in the U.K. to tie the cost of auto insurance to the miles driven by a driver. Norwich Union, the U.K.'s largest insurance group, has a Web page descibing this option. The program leverages the location services available in today's mobile phones to track drivers' movements. If this makes enough sense, and if privacy concerns don't torpedo it, we'll see the idea spread worldwide, having a beneficial effect on encouraging alternatives to getting behind the wheel of a motor vehicle.
