I'm about to drive to Bathurst, which is about 150kms (but three hours, due to the slow roads) west of Sydney. Every time I drive west I look at the endless stream of cars driving slowly towards Sydney, many of which are occupied by just a single person.
And recently it has made me think about a brilliant idea, Avego...a car pooling service that uses GPS and mobile phone technology to connect empty seats in cars with passengers needing a ride.
Ok, so this scheme is unlikely to be the solution we need in its current form. But that's not the point. Great innovation is sometimes about triggering the thinking that will ultimately lead to the solution. Because increasingly it's not the first to market that dominates but the right product to market (don't forget, iPod was not a first by a long way).
So check out Avego, and get thinking.
UPDATE...Seth Godin posts here on another great idea for an iPhone/GPS driven piece of car-travel innovation. Now let's wait for someone to put the two together and make it all work...
