Current highway developments include driverless cars and
electric motors. Further plans are closer to the ground, that is, the tires. Important strides have been made with the safety
and lifetime of traditional tires. A fascinating, possible next step includes the novel idea of spherical tires. Just imagine
ball-shaped tires which can rotate in any direction. Such a vehicle could slide from lane to lane, spin 360 degrees in place,
and move sideways for parallel parking. The vehicle would be suspended slightly above the tires by magnetic levitation. That
is, the computer controlled tires would not be in physical contact with the vehicle.
