How resilient are wooden telephone poles? A car hit a pole mid-block, several of the lines fell off of the?

poles, & their weight twisted (& bent?) the pole on our corner. I could see the twisting in the pole before they re-righted everything. Someone who was out there when it happened claims that they heard the pole *crack*. So . . . I am wondering just how much such a pole can go through --it is an old pole-- and still be strong enough to be used. (There are 4 high voltage wires, and 1 thick telephone cable, plus one thick cable TV cable lower down. Only one high voltage wire stayed up, along with a guy-wire.) The workmen were told these things, but decided to go ahead & keep that pole. They only removed the one that got hit.
