That does sound like wonderfull progress.
Is it possible maybe you're only noticing it when you are in your garrage / dirveway (or wherever it is you are working on this)?
It's a shame about the 'bratty' behavior of the 13 year old (sounds like he's a 'time out' kid; I would have got my but kicked for that, then a whupin' when I got home too, my how times have changed
).
As far as the 'stupid driver tricks' my stuff is hard enough to see from the street that I don't personally have that problem but I have heard of that kind of behavior (revving engines as they pass, burnouts, or as you describe, alsways leaving the stop sign like it's a 'Christmas Tree') from many people.
Even to the point of, if their garage door is open (tarp is off, whatever it takes to make it visible from the street) that it's like a switch for such behavior.
Kinda like a full moon, people only act goofy if they can see it.
Keep up the good work.
