I've updated this mod to be 2.0 compatible:
https://mods.factorio.com/mod/VehicleGrid2
However, if the original author (Optera) wants me to take it down, I will do so, as all I've done is make minor changes to make it compatible with Factorio 2.0.

A better version already existed:

You say that, but I looked at it and didn't like it. Sure it added grids, but it looked like it was adding all sorts of other stuff and restrictions as well.

The only difference, aside from the new Speed Booster equipment taking the place of exoskeleton legs in wheeled vehicles, is having more fine-grained control over the grid sizes for each type of vehicle, and preventing incompatible equipment from appearing in certain vehicle types.

Apart from the speed booster equipment replacement, these are both user-facing improvements over the original mod; there are no unnecessary restrictions added.

I'd compare the original mod's approach to that of a blunt hammer, simply slapping on an equipment grid to all vehicles equally without any regard for the end result, while my version's approach was far more refined. If you had actually tried it out, perhaps you would have realized this.

EDIT: Yeah, I suppose he got me.

I was considering implementing a setting to disable the speed booster equipment (which I would argue, has much more value and purpose than is given credit below, but that's besides the point), based on their suggestion, but having a simpler alternative is probably better for everyone involved than attempting to reconfigure the primary purpose of my own mod.

I rescind my previous comments, and apologize if it came off as hostile

Or, I valued not having to deal with another item that's only purpose was a mere visual despite it doing the same exact thing as an existing item over just having simple features. If that was an optional feature, I could concede that it is better. But as it is not, the use case is not the same. And if it is, that is not clearly stated in the mod page, which should be giving me that info before hand.
