There have been some questions about whether the auto-presenting front doors will detect and stop short if another car is parked close. We know the falcon wing doors have ultrasonic sensors and will adjust before hitting anything, but what about the drivers and passenger doors? Some say they are just resistance sensors and won't stop until they hit something. They normally swing open 45 degrees on their own. What happens when another car parks too close? Well, we got to try with forum member Kittylitter's brand new Sig X this morning. Either they were extremely brave, or extremely oblivious to the goings-on. Either way, they were extremely generous with their time and car. I filmed the results: It stops!
