I don't understand people's reluctance to just get the right glasses. Bandaiding with readers and such is a hassle, wearing glasses all the time is not. Often while driving you are going to want sunglasses.
I admit I come at this from a place few other do, I have had bifocals since I was 10yo my first pair of glasses. I have safeties for work, yardwork, home improvement, auto maintenance, regular for home and sunglasses for fishing and driving. Once you are used to wearing them and leave them on your face all is well.
I remember my Dad struggling with getting used to wearing them, taking them off all the time lead to losing and breaking them.
Far as field of vision with a progressive go to a good optometrist with knowledgeable staff tell them about the oddity of the car screen and they can help get the right shape lenses. Shape of the lens matters, a wrapped lens or a small one might lead to distortion. I have had knowledgeable staff shoot down many a frame choice on my part because they knew it would cause distortion with my prescription.
