There are even some police in my area that uses conventional land surveying equipment and rapid high density laser scanners. Precise measurements of things like skids marks and other evidence of how the vehicles came to rest can be used to estimate initial speeds and confirm or refute the testimony of witnesses.
It could also be something more mundane like an actual land surveyor collecting data to support future design work or verify completed projects.
Neither of these are jobs that can be done at night or at times more convenient for your car.














They’d probably eat this up in one of those liminal space communities.
