Joining the cheers, I love this functionality!
I always liked going around in a car to build and fix things. It feels more like being a real engineer. But the vanilla way of driving quickly spoiled the fun. One may as well use a construction train, but they are a lot less flexible - can never leave rails, no sharp rail turns. After downloading the assist, I set up some road connections between my production centres and outer walls, and it even looks natural.
It's amazing how Factorio manages to be such a wonderful building kit. Take your most-loved blocks and play your own little game in the game. As of this mod, I'm now contemplating setting up racing tracks like slot cars :D
Thank you Branko for updating and thanks to the original authors for setting up the "PDA" ;)
