Is the PC page bad? Yeah, it's typical marketing with bad grammar. Is this video good? It's not bad, but it's still marketing and does exactly what a competing product would do. You're not going to get a straight answer from either company about any competitors. When I talk to customers I don't say, "Yeah that product is actually really good and pretty much does the same thing as ours. But buy ours because I asked so nicely!" I'm going to pick apart every single little flaw and blow it up so all the good/normal things it does compared to my product seem inferior by comparison.
Anecdotal here, but the only time I've ever run into an issue with my PC is when I stupidly changed modes while in Drive. Luckily I was just sitting in my driveway with my foot still on the brake, but I just wasn't thinking and changed it. PC says you're not supposed to do that, and it makes sense. Those issues people had at the 8 minute mark all sound exactly like what happened to me when I changed modes in Drive. Again, something PC says not to do.
I personally don't want the pedal changing without my input when I'm driving. Why would I want different sensitivity between reverse and drive? What happens when my wife gets in the truck, reverses out of the driveway/parking spot on one pedal setting, then has Sport+ or whatever I chose when moving forward and slams into my mailbox/a car? Terrible idea.
