It would be very handy if this mod could recognize the roads from Transport Drones for driving - presently it actually ends up getting confused by them, all the more if there are e.g. concrete next to the roads because it will try to steer the vehicle to drive on that instead. Thanks for considering!

I had the same thought, and it looks like it's super easy to add support :)
Add the following line to config.lua line 247 (as of version 2.2.0 of the mod) - and it works:

["transport-drone-road"] = scores_values.asphalt,

Me too! I've been using the PDA just started another two playthroughs (solo and duo) and wanted PDA to work on Transport Drones road tile. Had to work around trains and helicopter mod, I just want to use the car for the beauty of easy driving in base. I don't have to be forced to use VehicleGrid mod instead when I can use PDA (I prefer a balance of OG Factorio with a smart QoL tweak that is lore-friendly/sensible to me). Please make this change! <3

Wonderfully designed mod by sillifly, and thanks for keeping it alive Arcitos. I hope the support continues.
