I do indeed have that. Although this solution would come it handy for the times I forget to immobilise via the app and also, if someone steals the car by dragging it out of the garage or putting it on the back of a tow truck, I can see where it is. Often when we go to car events (say at Silverstone), they are far away and we spend an evening in a low cost hotel near the motorway. If someone puts your car on a tow truck in a place like that, it really will not look out of place and would be the easiest way to steal a car! I have been known to clamp my own car :D . One time I had a young lad come up to me in the morning saying “Oh mate!!! Can’t believe it! Those bastards! Why did they clamp you!?” I said “Watch this!” and pulled the key out! We both laughed a lot!
