You don't know what you're talking about. It takes an enormous change in temperature to cause enough pressure change to in turn cause a blow-out. Clincher rims and tires will hold far more pressure than you think. These two factors together make this practically impossible unless some user error already exists to be exacerbated (it should go without saying that this is also a risk with tubulars). A heat-induced blow-out is flat-out not possible in a crit, or any typical bike race. On a massive, steep descent the necessary conditions can be induced, but these same conditions are going to make your tubular glue soft and tacky as well. Either way, I would recommend using equipment that gives you confidence and making sure that your health and life insurance premiums are paid up.

Wobbly though.
I now go 90 PSI, try to find shade, and deflate all my tires that will be sitting in the car.

FWIW: Left two aluminum clinchers sitting in the wheel pit (concrete sidewalk) last year in the Texas sun. Had been inflated to 110 PSI. Both blew out. Lost two sitting in the car also.

Nothing wrong with replacing for peace of mind, of course, but you're not doing anything different than any other crit racer for tire wear.

I would think it depends strongly on tire/rim combo. It's supposed to be impossible to roll a clincher, but I've done that too.

I had a guy roll a clincher next to me in a crit.

Been at work too long, I clearly forgot. 
I, too, have had tubes spontaneously flat when I've left them in hot cars or in otherwise enclosed spaces, just to add to the general theme.
My argument for getting tubulars is that you get to sit around, sniff glue, and probably have a few beers all at the same time while you figger 'em out. Sounds like a win-win-win to me.
