This ran in the NY Times and I thought it interesting and was in our local paper today.... I think all the girls need one!

Technical progress can be a mixed blessing, and so it is with a new patent by Yefim Kriger, a Connecticut inventor.
Kriger's invention, according to The New York Times, is a car that can weigh its drivers, keep track of the weight they've lost or, more likely, gained, and nag them in a friendly way about the extra pounds: "Oh, you're overweight. What happened?"
The device can recommend diet and exercise programs and project how much the driver will weigh in three months or three years, which is probably more than most of us care to know. If a driver obstinately continues to gain weight, the car can snitch on him to his doctor via e-mail.
Now, obesity is a serious national problem, and any new weapon in the war on fat is certainly to the good. But in a world grown relentlessly snoopy, the car is to many of us a last refuge - you adjust the seat to your shape, the music to your liking and the climate control to your comfort. The fact that you're also hopelessly stuck in traffic should be aggravation enough without the car's whining about your weight.
A redeeming feature of Kriger's in-car scale is that it can also weigh the passengers, a promising way to deal with another driving irritant - back-seat drivers
