Bosch Aims to Reinvent the Sun Visor

摘要

Not much has changed in the world of sun visors since they first started appearing in the early 1930s. Drivers flip them down to block the sun's glare-which is said to cause twice as many accidents as any other weather-related factor-then back up when they aren't needed. It's a simple and relatively effective solution to a common problem.But it isn't optimal. Visors aren't left down all the time because they can obstruct a driver's vision. And constantly adjusting them is annoying at the very least and, worse, may distract a driver's attention away from the road ahead.
