I'd like to see a HUD built into the windshield, one that puts "target" boxes around the cars in the view, and tagged with their relative speed vs. mine, maybe a 4-sec projection of direction, and a "rear view" of same.

That would be nice but a car under $200,000 has a certain allure.

[Political Junkie Too]

Don't the cars today already have sensors that alert you when you back up too close to an object? Weren't there car alarms a few years ago that went off when you approached a car? Don't cars have webcams so you can see an image of what's behind you?

How much would it be to integrate these technologies if you don't have to also wire them to a weapons system? Throw in a dual core CPU, an 8Gb flash drive, maybe a radar detector, a radar speed gun (Ramsey sells a kit for $70), and you're halfway there.
