Tesla working on Autopilot radar changes after crash

DETROIT (AP) — Tesla Motors is working on modifications to its Autopilot system after it failed to stop for a tractor-trailer rig in a Florida crash that killed the driver of a Model S sedan.

Experts contacted by The Associated Press say it's clear that Musk is focusing on the radar so his cars spot tractor-trailers in similar circumstances.

Radar can see through bright sunlight, rain, snow and other things that can block the sight of cameras, so it makes sense that Tesla would try to emphasize radar more after the Florida crash, said Raj Rajkumar, a computer engineering professor at Carnegie Mellon University who leads its autonomous vehicle research.
