Why does directioal signal go twice as fast

Normally the rate of blink being twice that of the normal rate indicates a fault in the system. At this point it sounds as if it is intermittent, in that you cannot visually 'catch' it in the act by getting out to check the blinkers when it occurs because it begins blinking normally again. It could be loose wiring in the directional indicator/light stalk, or in the door if it disappears when you get out to check if the lights are blinking normally or at the increased rate indicated on the panel. It can also be a partially dislodged relay responding to vibration and temperature, which is what I would check first, and make sure that all the relays are properly seated to rule out intermittent contact at that point in the system.

The most likely source of a loose connection is the plug that goes to the rear lamps assembly. Unplug it and inspect the plug for any signs of heat distortion on the plastic. Check that the teeth looking prongs form a straight row across the plug.
The end prongs on the inboard side of the connector is the ground wire for the light assembly as has a tendency to overheat and distort. You can use a small screwdriver to reshape the prongs bask into position. If it is showing signs of overheating you will need to add an additional ground wire.
Do a search for rear bulb failure and you will find a few methods for adding an additional ground. I had the problem on my 97XK8 and added the extra ground a few years ago and haven't had a problem since.

You're absolutely right on the cause of this doubled-up speed of blink.
The backup light(s) on either side will also generate a warning due to the ground wire deficiency. I'd certainly beef-up the ground wire for MY97 XK's
