I'm skeptical of the plan to provide a "kit" that can be put on arbitrary construction vehicles. I think Cruise tried something similar with personal vehicles and quickly learned it really could only build a system for a specific vehicle. There are tons of complexities associated with mounting of sensors and interfacing with the vehicle specific control systems.

Not saying it can't be done, but I wouldn't be surprised if the company has to pivot to supporting a subset of their goal and then gets bought out by some larger company to work on their line of construction vehicles.
