I realized that where I live I am very lucky as the temperatures are usually in the high 50's to low to mid 70's. However, if I venture out it can jump up to over 90 and when I drove to MFEST over 100 degrees.
When in high temperatures, in the high 90's and 100's in traffic, for me, it is much more comfortable with top up and AC cranked.
