Rick has nice videos on driver swings as well. Have a look at this one, for example, it sums the most important points up quite nicely:

That does look quite helfpul, and good to know the weight is 50/50 on the feet as well.
Do you trigger that movement similar to the irons, with a shift forward, with the tilt making you hit upwards? Or is there something else that activates that downswing......
