I don't think a regex can save you here. Ask yourself a higher-level
question. Why are you gathering the address information, and why isn't
it optional? If it's to send something of value to the person you're
requesting it from by postal mail, or if you're using it to help them
find something they need nearby their home, then rest assured they
will enter it with care.
If it's anything less, you invite this sort of abuse, and you should
either just stop asking the question, or realize that a significant
percentage of entries will be "undeliverable" (to use the Post
Office's bloodless euphemism).
By the way, I believe the USPS has an address checker API, IIRC, I've
used it from PHP before, and there may be a Gem wrapper for it as
well. Ditto FedEx if you're using them for delivery.

Hi there,
Anybody knows how to use regex to validate street name field? I want
to avoid things like "st asdkskjfls çsdfksçf".
Thanks,
Pedro
