The vehicle is in limp mode. Based on your description, it's because a speed signal is missing somewhere so the car does not know what to do. As a result, it locks up to let the bicycles go past safely. It could be the brake switch which is built into the servo, the ESP module itself. You need to have the computer scanned to identify which is the cause.
