The Road Train: How much time and money could this save?

You’re stuck in traffic on the way to work, as you are every morning. Glance around and even those responsible rides with multiple passengers have one frustrated driver just like you – tapping the gas, hitting the brake, tapping the gas, hitting the brake. It’s an utter waste of high productivity morning time for every single one of those drivers. A machine should be able to just keep up with the car in front of you, following its speed and turns. In the meantime, you could join your passengers in reading, handling email and non-distracted phone calls.

The hope is that average road speeds can be reduced, improving fuel consumption and cutting congestion.

Here’s how it works:
