So what about Ford's home backup system?
All you have to do is park next to the chicken coop.
Nikki Gordon-Bloomfield from Transport Evolved has had nothing but problems, but after working with Ford for many months she finally found the solution. She had to back the truck up next to the chicken coop to get it to work. Seriously. The chicken coop.
And even then it's not reliable. Those lazy chickens!
Essentially, this product relies on Bluetooth instead of communicating over the wire. We all know how flaky Bluetooth is. Plus Ford put the Bluetooth receiver in the wrong part of the truck so it's far away from where you plug it in to the system it needs to talk to. So she has to park in just the right spot for it to work.
Quotes from Nikki:
A home backup is pretty useless if it's unreliable. The best thing about Tesla's system is that it will actually work.
