I stalled it a couple of times just after collecting my Antara but it was just me the handbrake etc wasn't even on. It just took a few minutes to get used to it.
Even with the hill start and electronic handbrake you should still be able to pull away without any problems.
It's the first car I have had with an electronic handbrake but it think it works well. Saying that I always use the button to release the brake rather than just driving off and I'm not in the habit of using it unless I'm parking and switching off.
The hill start always seems to work perfect for me others can't seem to get it to work for some reason its either the car or people's driving style I'm not sure.
