I have no troubles with ice as long as no other moving objects like other cars are around.
To test if its too icy to use the breaks tap on them and if its icy the car will immediate slide for that short period.
In that case take your feet off gas and let the car naturally slow while you have control of the steering.
Slamming the breaks on ice is near suicide.
When my kids were learning to drive, I took them to an empty, icy parking lot and showed them what happens when you slam on the breaks. It was the best lesson I could teach them in snow country.
Tapping your breaks on black ice is not a good idea
IF the road is iced no one can stop until they run into something
