This is how I feel about the situation:
1) In an auto - just touch the brakes unless you're stopping for extended periods. I can't be faffing about with sticking in park, putting parking brake on etc etc at each set of traffic lights I get to
2) In a hybrid, better off going into park rather than neutral otherwise the hybrid battery wont charge
3) Manual - I got taught to stick car into neutral and put parking brake on. And then I started driving and binned the idea for a few reasons. Firstly, it takes the mick when a traffic light only lets about 3 cars through and theres a big queue and everyone is fiddling about with their gears and handbrakes. Also, having driven my first car without using the handbrake at all unless stopped for more than 5 minutes, I can safely say that the clutch didn't go in 90k miles. No idea what happened after I got rid of it but this scaremongering of "OMG your clutch will burn out" is BS.
4) OK so you can dazzle road users behind you - seriously? Im in stop start traffic and hardly anyone uses the parking brake on cars like Audi A7's and A6's etc, basically cars which are likely to be automatic and ive never been dazzled
