I agree your life sucks, but I also think if she was driving the same car previously for 10-20 years and the previous car didn't have the 'creeping' thing most cars had/have, she may really not used to it. Over the several cars I've owned, the movement with no petals pushed varied in speed and power depending on the age and type of vehicle. Most Automatic cars have it, your transmission is built with it. But some used to not to have it!

That was the second hardest thing about switching to an automatic for me. Have definitely almost hit people. (actual hardest was resisting the urge to stomp on the parking brake when coming to a complete stop)

And this is why old people shouldn’t be allowed to drive. Even if she’s not “used to it”, you think after realizing it does that, she’d keep her foot on the brake and not take it off.

All the comments on here make me question why people are taking their foot off the brake when they're stopped anyway, automatic or not, unless their cars have an auto- function... Even if the road looks flat there's still often a slight incline that means you could roll. and if someone rear-ends you, if you've got your foot on the brake you might not hit the car in front of you...
