SkyTran is a big change in how we travel:

• in cars that drive themselves, 
• weigh a few hundred pounds instead of tons, and 
• hang from thin elevated guideways, riding on magnets instead of tires
  

that brings big advantages:

• 100-MPH travel everywhere, with no traffic jams or parking hassles (vehicles always waiting for you)
• Vehicles  drive and park themselves
• 200-MPG economy, in renewable electricity instead of fossil fuel
• Guideways have the capacity of a 3-lane freeway and can be built in weeks at 1/5 the cost of light rail or freeway
• Nearly silent vehicles on tiny elevated guideways don't disrupt neighborhoods
• Naturally safe and handicap-accessible
