Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter
Folks have been riding steel bikes in the rain all over the world for about a century. Yes rust can be a problem, but not a serious one, because paint so effectively prevents it.
You might want to go an extra mile in terms of rust protection by spraying the inside with a light oil sealant, like Boeshield, LPS-1, or even WD-40. You can also buy JP Weigle framesaver which is made specifically for protecting the innards of steel bike frames from rust.
In my experience, paint does a great job on the outside, and internal rust was ever a problem except on bikes ridden in the winter where the cold caused condensation on the inside, so I only oiled bikes used in the winter.
BTW- your steel car spends lots more time out in the weather under much harsher conditions, and lasts 10-15 years before rust becomes a serious issue.
In short ---- don't sweat it.
