Tasker will work but not based on speed, there's no setting that i know of that allows your to trigger something based on your speed from the gps sensor. I have mine set that if wifi is disconnected it will turn on bluetooth, so if i leave home or work and im not connected to wifi anymore bluetooth will turn on and it'll connect to the car.
if your phone has an nfc reader you could use tasker + nfc
Its a Sgs3, and it have nfc, will it work then? is there a specielt setting to use?
read this article. you'll need to buy NFC tags, but they're pretty cheap and the end result is awesome.
