I'm actually relieved no one has commented on the weight being unsafe, like in the wired comment thread. I'd just like to point out that some titanium alloys have the same strength at only one-eighth the weight of the strongest steel alloys. However the titanium alloy only carries one-eighth the kinetic energy and would greatly increase road safety if used extensively in cars. I mean if a pickup weighs 4,000 lbs, and it can carry 2,000 lbs of materials before it doesn't have enough torque, reducing the trucks weight by 50% and not even changing the engine would mean it could carry 4,000 lbs of materials before it doesn't have enough torque. That's a highly simplified explination, but the general principal is there. Any weight not wasted on the chassis, means the vehicle can tow/carry more at the same fuel consumption rate. What's even better is, like the 1L, if you make your car lighter you increase fuel efficiency greatly. I mean I wonder how many Ford F-150's are out there that spend half their time wasting fuel as they're pulling around 2,000lbs of chassis they could do without, and could do with another 2,000lbs of extra carrying capacity when they are working.
