The temperature on the road is different than the air temperature. A
lot of traffic or thawed ground can keep the road surface wet/warm when
the air temperature is below freezing and a hard frost can keep the road
frozen when the air temperature has warmed up.

Sun also has a 'radical' affect on the surface temperature of a
vehicle. So does your vehicle's heater. The rear door of our Cherokee
can be frozen up and the vehicle's heater will eventually warm it up
enough to melt.

I'd guess that the "car wash" warning had more to do with it not getting
broomed off by the RoboWash brushes.

There can be a fair bit of difference in temperature with just a few
feet of elevation change, and the air can be a good deal warmer than the
surface you're driving on and it can make a difference -- 33F vs. 31F.
If I were using it as an icing indicator I'd want it down by the
pavement surface.

FWIW, the outside sensor on the ZJ is located behind the front grill.
One of the verticals blocks the sensor from direct rain and it's about
1" from the radiator. Works well there. The fan sucks outside air past
the sensor so the radiator doesn't affect its reading.

I think what it comes down to is there is really no good place if you want a
true air temperature.

Anywhere on/underneath the vehicle will be influenced by heat radiation from
the roadway. Fresh blacktop in the summer sun will be much hotter and even
in the winter the sun will make the roadway warmer than the air just a bit
off the road.
