You can hang a bed sheet and drive towards it at 20... so if you don't trust it what's the worst that can happen...Hey, since I got mine with FCWwBS I was wondering for a while how would I ever know if the system works at all, unless I get into a crash or really dang close to a crash. Today I was driving (35-40 MPH) and a Lexus RX (yes, I know right?) in front of me was about to turn right but in the last second he decided not to turn but to continue straight and magic happened, beeps and red LED's went off meaning Fusion was actually paying attention. I was paying attention as well so the situation was not dangerous but I was glad that whatever software or AI this thing is using it made a right call.
Just wanted to share this with the Forum. I know Ford has very good FCWwBS and gets Superior rating by IIHS but all that is nothing until you personally experience it.
And yes, I gave my car nice pat on the A-pillar when I got home...
