I'm not sure how you accomplish that, unless you have a parking garage for your air-conditioned car, in your office building.
Many hot and humid days, I come back from lunch, just having walked 3 or 4 blocks, dripping in sweat. And that's the distance to the closest public parking lot too ...
Working downtown, I'd even change to use transit, before the streetcars were air-conditioned.
For some times of the year, showers are cycling infrastructure. They are useful for other things too - I used to shower in the office after having played soccer over lunch hour.
