I don't buy that at all. I think you are making excuses. Life was feasible before air conditioned automobiles.
If you shower before you ride then you have twelve hours or so head start on bacteria - it takes them that long to multiply, excrete and cause a stink. So even if you are glistening with sweat at work then you can change your clothes, wash your hands and face, sit at desk, work, no smell needed. If you do stink then maybe it is because you lack fitness and basic hygiene, which is nothing to do with there not being a shower at work.
When was the last time anyone washed a seat in a car? Never! A car seat is one of the most disgusting places to sit. Would you not change the sheets on your bed for years? No. Yet sit in the same seat in a car, year after year, with a greenhouse around it, sucking in carbon monoxide from the tailpipe in front - no idea why people think that is hygienic.
Hah, right. I'll gloss over the number of assumptions about me that you make and we'll just address the real crux of the issue.
Biking 15 miles to work is not practical in 100+ degree weather with humidity averaging between 60 and 90 percent. Moving to be within biking distance of work is not practical when jobs change every few years and there are two of us living in the house which is fairly central to both workplaces.
And I wash the interior of my car yearly - your phobia about 'dirty car seats' is fairly silly.
I'm curious. Isn't the breeze you get when biking enough to cool you down? I live in Denmark and we don't often have that kind of weather, but the breeze that you get when riding your bicycle can be really nice in the summer.
I've only experienced Dallas summer heat, but no the breeze doesn't help. I would leave work and it would be ~105 F (40.56 C). I'd get in my car and roll down the windows until the A/C started working. The air that came in while driving would feel like the same temperature as the air in the car, like a hair dryer or something. It was like an omnipresent inescapable oven. Imagining THAT with 80% humidity sounds unbearable.
I'm going to assume that's 100 degrees fahrenheit, right?
That's around 37 degrees celcius for us non-US people =).
I'm from Sydney, and we often have low 40's (Celcius) during summer. We currently have raging bushfires over here in some areas =(, and it's easily 40 degrees.
I bike to work (and also for fun on weekends) during that sort of temperatures, and I've never been worse for wear...
I also jog regularly during that weather (although I find that harder than biking - less breeze).
Mate - you're not going to get heat stroke from riding your bike a few Km at 37 degrees, seriously...
As your fitness improves, you'll probably find it easier.
Just stay hydrated (you do carry water, right?), apply sunscreen, and you'll be fine. Sure, it's harder work than driving a car, but exercise is hard work (despite what those late-night TV ads tell you).
Yes, you are right. I live in Houston and I bike for 12 miles round trip almost through out the year except when it is cold and windy. And if you are commuting for work, you are not going to face the peak heat in the middle of the day during summer. But the roads are not completely bike friendly in here and there is problem of stray dogs.
I'm not exactly disagreeing with you, but humidity makes a HUGE difference. I've been in 100+ degree heat with low humidity (115, actually (46.11 C)) and it's downright pleasant. I've also been in 100+ degree heat with high humidity and it's almost unbearable. The difference is, in low humidity your body does a fantastic job of cooling yourself, while high humidity prevents your body from dissipating as much heat since your sweat doesn't evaporate. I'm not saying you're wrong, but temperature does not describe the entirety of a climate, nor its safety.
First you call this guy out then make the declaration that people don't wash car seats because obviously you do not. I have the interior of my car washed thoroughly no less than twice a month and my commute is only like 4 miles round trip so it is always thoroughly clean. Stop making assumptions based on your own warped view of reality.
