DW here. I too drive, a little, when we take trips. DH even had me drive into a gas station and back out, around the back behind the drive in restaurant, where we stopped and ate, then back onto the interstate. I drove to the next rest stop where he took over. While he drives, he teaches me things like keeping an eye on the side mirrors checking that that we stay within the lines, letting off the accelerator going down a hill, and accelerating in anticipation of an incline, staying on the outside lane when making a turn, turning wide, how far back to stay behind others, how to pass safely, etc. It helps because you never know when I have to do it as he says.
