I have a push button, but i still have to stick my dongle in the dash.


But a big point is overlooked here...

having a push start button also makes it easier to optimize the start through electronics.
You get in
you push the button , done

some people would floor the accelerator when cranking, some would pump the pedal, some would crank a bit to short, some to long.. etc etc..
No more of that , now you simply push the button. From an engine control point of view, it's better.

Obviously you want a system that works, on a car that doesn't go loopy and on the run, with defunct brakes, but that's a whole different story...
