1. A vehicle guidance system comprising:
- a first vehicle comprising a first lane position detection system having at least one of a first camera, a first radar, and a first lidar, wherein the first lane position detection system is configured to detect a first path of a second vehicle as the first vehicle and the second vehicle travel on a first road;
a third vehicle comprising a second lane position detection system having at least one of a second camera, a second radar, and a second lidar, wherein the second lane position detection system is configured to detect a second path of the second vehicle as the third vehicle and the second vehicle travel on a second road that is located remotely relative to the first road;
a computer system having at least one processor and at least one memory comprising first program instructions that when executed by the at least one processor are configured to numerically analyze collective path evidence comprising first numerical position data indicative of the first path from the first lane position detection system of the first vehicle on the first road and second numerical position data indicative of the second path from the second lane position detection system of the third vehicle on the second road to determine a collective veering characteristic of the second vehicle; and
a communication system configured to send a first wireless communication to an antenna of a fourth vehicle in response to the collective veering characteristic exceeding a first veering threshold, threshold, wherein the first wireless communication is configured to at least one of warn the fourth vehicle regarding the second vehicle and prompt the fourth vehicle to alter a first driving route of the fourth vehicle to keep away from the second vehicle.

Abstract
A vehicle guidance system can include a first vehicle that has a camera, radar, and lidar to detect a first path of a second vehicle as the first and second vehicles drive on a road. A processor system of the vehicle guidance system can analyze a first deviation of the first path. Measurements from another detection system can provide additional data regarding a second path of the second vehicle. Analyzing the first path in light of the second path can enable the vehicle guidance system to identify impaired driving indicators. The vehicle guidance system can warn vehicles about the impaired driver.
