Can't you use the clutch and foot brake smoothly enough to take off on a hill? Even a slippery one? Hand in your manual transmission driver's licence!
[Tidbit: where I live drivers are issued with different licences for manual and automatic cars. You have to pass the test in a manual car for that licence, otherwise you can only drive automatic cars.]
My 1987-ish Subaru RX Turbo had a hill-holder manual, and I think the company had been making them for a number of years even before that. Major confidence boost for a high school kid living in the hills, and learning to drive in that fragile, overly complicated used car he could barely afford to insure let alone wreck.
I've burned my clutch so much doing that, now I put the 4x4 into "granny" low, and just quickly move from brake to gas and drop the clutch. It rolls back only a couple inches. But I really should put more effort into the heel-toe.
