I don't often use my handbrake but mine doesn't release on just pressing the gas pedal. On my journey to work there are traffic lights on a hill, I always get a red!! I have mine in neutral, with the brake pressed, (no handbrake) clutch in, select 1st, off brake and over to gas peddle, no roll back at all.
I had renault that had electronic handbrake, I found that after 18k miles I needed new pads and disks just on the back I put it down to the way the electronic disengaged, so on the Antara I knock it off myself.
