Police generally need a warrant to enter someones house too for the same reasons. However, if they chasing someone or there imminent danger they can enter someones house not search it, but it is only to deal with chasing the person or preventing the imminent threat. The only reason I see police deploying this would be to avoid a high speed chase. Where that ends up constitutionally I don't know not a judge or lawyer, but it is one of those imminent danger/pursuit situations the courts have carved for other circumstances. Now I will say if the police follow someone they are chasing into an other persons house and in that house see drugs. Under most circumstances that could not be used as evidence against the person that lived in the house since they did not have a warrant to search for drugs in the house. Their only legal reason to be there was to catch someone, so anything unrelated to that narrow purpose generally can't be used in court.
