Autofocus or manual focus when filming from a driving car?
I plan on filming a car scene in which one car is the camera car and the other is the subject car. Both cars will be moving; probably driving down the street and on the highway.
My question is which is better for keeping the subject car in focus: autofocus or manual focus? Or rather, which will produce better results in terms of footage produced?

I've been using manual focus up until now that I have to film from a moving car and I can't exactly control the environment this time. I will plan where to shoot, and how the cars will drive by each other but that might be about it.
Equipment used is a DJI Ronin and Sony a7s series (most likely a7sii) cameras with Atomos Ninja Flame. I'm not sure which lens yet as I will base it on whether I use autofocus or manual focus. I won't be able to control the zoom either and refocusing will be difficult as I have both hands holding the Ronin.
Any help would be much appreciated. Thank you!
