Wayve says self-driving cars don't need sensors. Experts aren't so sure.

Why weigh down a self-driving car with a lot of sensors, HD maps, and equipment when you don’t have to?
That's the philosophy of British startup Wayve. It claims it only needs a camera, GPS tracker, and a powerful computer to be able to drive anywhere autonomously. 
But experts who specialize in sensing technologies like light-based LiDAR and radar say the idea mostly comes across as preposterous — or the very least, short-sighted. 
Most self-driving cars decide how to driv
