Now that I'm back in Israel I find myself behind the wheel a lot, and certain late nights as I'm driving home I also find myself singing along to some tune whose lyrics I can't quite recall. That's where my new idea - Car-aoke - comes in, a simple device that projects the lyrics on the lower part of the windshield, so that all those drivers singing off-key could at least get the words right.
Here, for example, is Beck's lyrically challenging Sexx Laws:

I don't think there should be any safety concerns as this should be no more distracting than subtitles in a movie, and could actually increase alertness on the road by keeping drivers alert and grooving. Email me and I'll let you know where to send your money.
