My comments: here goes!
1st: It's a Ford innovation. What more can be said (you can take that either "positive" or "negative") I do bet Chevy and Ram copy-cat it though!
2nd: According to the video link above, it looks like it works pretty good for backing a boat! BUT ... a 35 foot TRAILER! Well ... we'll see eventually!
3rd: It's quite obvious the driver in the video has practiced with this device for a while. It still takes time to figure it out. Either watching a monitor or looking over your shoulder, you've to to figure out which way to turn that knob. Coming from "old school" here, I think I would be terribly confused with that knob and the direction to turn it. So the person doing the driving in the video, of course, has had lots of practice to make it look so easy. For us "old school-timers" I bet we'd get frustrated very quick with this!
4th: I do see an advantage to this technology. First, its a new innovation and I'm sure Ford is going to make a lot of money off it from folks wanting it installed on their vehicles. (you know, children always to play with the newest and greatest toys on the market). Second, for someone who has minimal experience towing and backing a trailer, and not "old-school", this may actually be easier for them. Third, it's raising some eyebrows (even mine), causing a lot of discussion now, giving us something "new" to talk about. All of these are good "positives"!
(Imagine "THIS" coming from a Chevy die-hard guy! Maybe I'm not so "die-hard" after all? Nay! I drive a Chevy, but do appreciate technology when I see it!)
