Buick added a host of safety features for 2013: a standard backup camera and optional cross-traffic and blindspot alerts to the Verano, a standard front-center airbag for the Enclave and optional forward collision and lane departure warnings for the new Encore. An interesting tidbit: Rather than repurposing the radar from adaptive cruise control mounted near or in the car's grille — often the way collision warning systems work — the Encore sees oncoming obstacles with a windshield-mounted camera that takes 10 to 12 images per second.
"It looks at the change in size of [the] object as you approach it," GM safety engineer Ray Kiefer told us last week. "It works much like the human eye."
The system doesn't engage automatic braking, which some do. But it could help avoid fender benders and lower repair costs for the ones that happen.
