Side note on "law". I was learned in my law class today that:

You can be pulled for only 2 reasons, with intent to be citationed, and intent to arrest. The cop is allowed to search without warrant only when pulled over with intent to arrest. If the cop pulles you with intent to citation (running a redlight, whatever) With "probable cause" he can search you, BUT he can only search your car in the area that he can reach with his hands from your seat.. like under the seat, beside/behind the seat.. etc. He is not allowed to look in your trunk, or in your LOCKED glove box.. because those areas pose no threat to endanger his life. AKA you reaching for a gun or something of the sort.
