^^ in this case, it makes perfect sense.
In a roadgoing car, where there is still a viable steering lock and keyed ignition switch in place, it just seems redundant, and a complete waste of time.
A turbo timer is very much a convenience luxury. An extra "button" to activate the starter is just that... extra.
Hell, you can put a pigeon playground aluminum wing on your car and justify it as "functional". You can put SOLAR PANELS on your trunk, because you can't figure out what's drawing power where it shouldn't. It's functional. They serve a purpose. That doesn't mean it's going to be widely accepted as a "cool" thing to do.
Cars that are built with pushbutton start usually have other features, like keyless entry, remote start, automatic locks, and NO KEYED IGNITION SWITCH. While i have remote start, keyless entry, and automatic locks, i see these as non-redundant luxury/lazy items. I still have a factory keyed ignition switch. Having to turn your key, only to have to also push a button to start the car, just seems like a colossal waste of one's time, both for the install, and every time you want to start the car.
Then again, i'm the kind of idiot who will buy a 12 to 5v converter, just so i can use a boost controller's accessory inputs to monitor voltage, fuel, and oil pressure, all on the same unit, simply so i won't have to install three other gauges. I like to have things wrapped up in a nice little package. Not strewn all about the dash and interior. Having the start switch integrated into my ignition just seems like the smart thing to do. Maybe that's why nearly every car manufacturer since almost the beginning of time has done it. Of course, the new keyless ignition systems are nice. However, putting a pushbutton in the car to activate the starter doesn't even come close to mirroring such a setup.
Maybe all the cool kids put buttons in their car to activate the starter. /ubbthreads/images/graemlins/dunno.gif
