Not for just that reason, but test him and he will find a reason to search your vehicle. This is not to suggest that you should just blindly accept such a demand. Constitutionally speaking there are few reasons any law enforcement officer may search your vehicle; chief among these is probable cause. Without probable cause, his legal options are limited.
yes, but only after they arrest you
Yes
yes, if you have a warrent out then they will search the vehicle.
no
Unless the officer discovered probable cause during the traffic stop (or had probable cause prior to), then no, the search was illegal. The officer would have needed to obtain probable cause to search the vehicle, in reference to Carroll v. United States. The prior answer referenced "Search Incident to Lawful Arrest" and that was incorrect. During a traffic stop for speeding, generally, no one is being arrested, and "Search Incident to Lawful Arrest" only allows the the officer to search for evidence related to the arrest, which for speeding, there wouldn't be any such evidence.
If a vehicle is searched without the permission of the owner, the officer must have some other justification for the search. This can be probable cause, search incident to arrest of an occupant, inventory prior to towing, abandoned vehicle, or other reasons. If you can show that none of the these circumstances existed when the search was made, you may be able to have the evidence obtained from the search suppressed in court.

Search of a vehicle in conjunction with a lawful arrest.
If the warrant orders a search of the vehicle, yes. If the bench warrant calls for the arrest of an individual who just happens to be found operating a vehicle when arrested, the area in the immediate vicinity of the driver may be searched. If the vehicle, subsequent to the arrest, is impounded for "safekeeping" then the entire vehicle may be searched " for inventory purposes."
good luck.
It's when the cops get a search warrent and then they search you and arrest you.
Yes, but you never HAVE to enter their car unless you are under arrest. Unfortunately, if you ask, "am I under arrest" the answer will usually be yes even in situations where they would have let you go.
