Am I being unrealistic here? I'm trying to make this system work given the options I have. Every other car that has a push button start, you have to turn a **** for it to work and I don't want to have to go that route because at that point, what the difference between doing that and turning a key. I don't think it's too hard to have to press the brake to start it or turn it off. You don't slam your car into park while it's still moving, you come to a complete stop and then do it so you already have your foot on the brake. Same for when you start it. You have to push on the brake to put it in gear. I don't think that what I'm proposing is all that difficult to do.
Also, I'm working on limit switch setup to make sure the car will not start with it in gear. I can't post much about it right now as I haven't tested my approach but when I have it working, I will let everyone know. This is pretty much because I don't want someone suing me over putting their car into a tree or something.
First off I am in support of your project. You have competing demands and are not going to be able to cover everything and make everyone 100% happy about every single aspect of the project.
Maybe missundertood the "starting" of the car. I thought that you were going to use the MB key-less-go shifter with integrated start button at least for the automatics. The proximity sensor and keyfob being required for security. Which is why my whole stance on the not having to use the brake.
Now it sounds like we are using the keyfob to do everything.
Which one is correct?
No matter the answer I still dislike having to press the brake pedal but it is far from a deal killer. It is a minor annoyance - like having to keep a key turned until a car starts instead of being able to turn and let go. Something you never really think about until you don't have to hold the key and we are talking about having to keep the key turned for less than a second.
