When you are given warnings about exercising in this type
of heat and humidity does it keep you from cycling?

No. I know a lot more about bicycling in the heat than those who issue
the warnings.

I am driving my junk car today without air conditioning

I am much happier riding my bike to work than I would be if I were stuck
in traffic inside some old junker with no A/C.

Heck, I'm happier riding my bike anywhere than being stuck in traffic
inside of a nice car WITH A/C. People think I nuts riding in the
Arizona summer heat, then I explain to them...

1) The amount of heat you "absorb" is a function of the difference in
temperature between the ambient air and your body.
2) Even on a really hot Arizona day, the difference is only 10-15
degrees F (5-7 C) for a cyclist.
3) On that same really hot day, the inside of the car is going to be
MUCH hotter - at LEAST 50-70 degrees F (28-39 C) hotter than the
driver's body temperature.
4) The driver is going to "absorb" a lot more heat while the A/C is
trying valiently to bring down the interior heat in the car. Keep in
mind that everything in the interior of the car is "heat soaked" and
even when the air temperature in the car reaches human levels, the
seats, doors, windshield and everything else is still doing their best
to toast the driver's body. Some people drive with oven mitts as a
result (I'm not kidding).
5) Meanwhile, the cyclist is tooling along effectively sitting in
front of a 15-20 mph full-body fan. Assuming the rider's sweat glands
work, the evaporative cooling will keep the cyclist reasonably
comfortable - never approaching the thermal shock of the driver
entering a virtual automotive sauna.

Then I add that I NEVER get stuck in traffic, and that I don't have to
go to the gym to stay in shape.

You're forgetting that big yellow Sun, which is providing a whole lotta
heat by thermal radiation to the cyclist's body in addition to that of
conduction/convection from the ambient air, not to mention the infrared
shining up from that hot asphalt roadway below.

I had to put an insulated cover on the black plastic steering wheel of
my wife's car because it becomes too hot to touch in summer.

You don't really escape the sun sitting in what's essentially a
rolling greenhouse, either. And as I mentioned in another part of my
email, the driver contends with the heat radiating from his
heat-soaked car's interior.

Let's face it - either way you're screwed... ;-)

Pretty amazing to those who haven't experienced it. I saw on the
weather report that it was going to be in the 106-109 degree F
(41-42C) range all week, with lows in the low to mid 80's. D'Oh.
