product ideas

...
I am in the final year of a technology education degree course, part of
which involves designing a product and manufacturing it to prototype
stage.
The product has to be original, or better designed, than any similar
product
on the market. I am posting this message to a number of newsgroups in the
hope that someone will have a problem with a product they use, or can't
find
a product to suit their requirements in the market place. I would
appreciate
any (sensible) suggestions.



How about an effective means of delivering courtesy messages to other road
users? (i.e. I'm am ceading my priority, thank you and so on.)

Mostly needed on motor vehicles (other users can use hand signals to much
the same effect), but could be developed for use on other vehicles if demand
is there.

Would help make using the road easier and more pleasant.

Good luck with the project!
