It’s actually illegal, but the driver usually gambles that you don’t know how to get where you are going. (the shortest way) So they just take a longer way.

Most taxi drivers don’t use GPS. They already know the route. But sometimes, they know that certain routes might be shorter but get tied up with traffic at certain times of the day. In that case, they might go a longer route, but arrive in a shorter time.

wel realy most of them knows where most streets are since they drive them every day like to and from air port an dnot all of them take the long way
