Is a public entity liable for an injury caused by a motor vehicle accident?

"Except as otherwise provided by statute," a public entity is not liable for an injury, whether it arises out of an act or omission of the entity itself, a public employee, or any other person. Cal. Gov. Code 815. Under California law, since all government tort liability is dependent on a statutory basis, a plaintiff must plead every fact with particularity, including the statutory basis for the claim. See Susman v. City of Los Angeles, 269 Cal. App. 2d 803, 808-09 (1969).
