I'm working on an update at the moment, but the addition of "passengers" in factorio 0.16 requires a partial rewrite of some of the mods functions. After that, an update is only a matter of minutes.
Huge thanks for working on updating this mod. I was just staring to create a road network to get from place to place more efficiently (and then 0.16 came out), so getting Drive Assist up and working again would be fantastic. I use VehicleSnap at a pinch and although very useful, it's not the same thing.
PDA is now ready for use with Factorio 0.16! To make up for the time the update took to complete, i've added another feature to control speed limit signs via circuit networks. Have fun!
