In the industry, DRAC seems to stand for Deceleration Rate to Avoid a Crash rather than Deceleration Rate to Avoid Collision. There's nothing wrong with adding the abbreviation to the dictionary, but be careful not to spread the wrong metric name.

Further investigation reveals that "DRAC" was originally defined by Coupe and Ferguson (1976) as Crash Avoidance Deceleration Rate , with a derivative called Deceleration Rate to Avoid a Crash emerging starting with Almquist (1991).
