You can't bring autonomous vehicles to market without ensuring they are safe, but as the technology gets more complicated, safety testing and validation has proved to be challenging.
Autonomous vehicles are only as reliable as the test that validates them. Modern vehicle technology is pushing durability requirements higher, and that's created a need to go beyond the kind of trial-and-error testing that traditionally takes place on a proving ground.
Gerald Roesser, manager of a new test lab for Roush, an engineering, testing and prototyping company in suburban Detroit, says watching a test driver repeatedly drive around a track, stopping for maintenance fixes and waiting for bad weather to pass is too time-consuming.
Also, there are too many test driver bathroom breaks.
