Let's get that TV show Mythbusters to do a test!

Doesn't matter either way is too hot for racquets
When it is 93 degrees outside, the temperature inside a parked car can reach 130 degrees in 20 minutes.
With an outside temperature of 83 degrees and your window down two inches, the temperature inside your car can reach 109 degrees in just 15 minutes.
If the outside temperature is only 79 degrees, the inside car temperature can soar to extreme levels. A black interior can reach 192 degrees on a 79-degree day.

This is TOTALLY untrue. There is absolutely no way the interior of a car can reach 192 degrees from solar radiation. 129, maybe... but NOT 192!!!
There was an experiment on Science Channel that proved no matter how hot the ambient temperature reached, the interior temperature basically plateaued. I can't recall that specific temperature was, but it was no way near 192!!

Just repeating articles I've read. I'm not a scientist but I do know 129 or 188 or 192 is too damm hot for racquets.
There was also a study done by DSET Labs conducted in Phoenix, Arizona over a two-day period. DSET tested six green Buick Skylarks, each with the same interior colors and the max reached a high temperature of 188, more than 70 degrees hotter than the outside temperature.

I guess gut would become edible after an hour or so at those temps if you basted it right.
And how about those ~118 degree outside temps! :shock:

pics or it didn't happen...
I refuse to believe you until I see articles on this matter. 188? There was an article this week in the papers; temp inside a car was ~125 when it was ~95 outside. I live in Florida btw.

Wouldn't the thermo of some bags help your racquets somewhat?
lol 192?

Heat-Beating Choices for Your Next Car
Consider buying a light-color car with a light interior if you don't have one. Light colors don't absorb heat as much as black and other dark colors do. The National Safe Kids Campaign estimated that a car with a white interior can heat up inside to 135 degrees Fahrenheit on a 79-degree day, while the temperature inside a car with a black interior could go as high as 192 degrees. this was found on this page:
http://autos.msn.com/advice/article.aspx?contentid=4019065&src=Home&pos=Edit1
Temperatures can range anywhere from 140 degrees to an blood-boiling 192 degrees inside a car, according to tests done by AAA. http://www.practical-pet-care.com/article_view.php?ver=16
188 http://www.tyvekcarcovers.com/english/carcover2.html
How about 200. "The temperature in your car get up to 200 degrees, depending on the temperature outside, the kind of vehicle you have, and how long it has been in the sun." http://phoenix.about.com/od/car/a/summercar.htm

at first, but what keeps heat out, also keeps heat in.
In the long run, thermo bags are rubbish.

Why is it you think solar radiation is incapable of heating a material to the extent of it radiating back into the cabin air, warming it up to ?190F?
If it's a clear, sunny day, the ambient air temperature outside can be cool yet if the car has black seats and the cabin is well insulated....the inside air temp will keep increasing over time until the heat escaping via conduction through the windows equals the heat being radiated from the warmed material inside the car.
Basically the inside of a car gets warmer and warmer until heat escaping equals heat coming in (your basic equilibrium state). Most of it escapes throught the windows at first but after a while the heat from inside warms the car's chassis to the point where it too starts leaking heat to the outside. Therefore if you were to look at a graph of a car's inside air temp vs. time...you would see the temp go up and peak after several hours and then cool down a little and plateau once equilibrium is reached...and then cool back down as 1) the sun moves in the sky and gets lower = less intense solar radiation, 2) air temp outside decreases.
Since air is a poor conductor of heat...the transfer of energy from in the car to the outside is not very fast. So there's no reason to assume the car's cabin air temp can't reach 190F or even 200! Because it quite clearly can!
Theoretically, if a transparent glass box with some absorbing material inside of it like some black paint was a perfect greenhouse object (it didn't let any heat/energy escape from inside) and it was indestructible (because it would eventually explode or leak somewhere from the tremendous pressure inside), solar radiation going in would continue to heat the air and increase air temp. indefinitely ...so it has nothing to do with just solar radiation being strong enough, it has to do with a constant stream of energy entering the car and being absorbed and reradiated back inside the car faster than it can escape.

Oh and you said you couldn't remember the plateaued temp? Well there is no one number because every car is different and will therefore have a different value...so don't know what you were talkin' 'bout there buddy.
