In my opinion, the best transport is a helicopter. Although, there are not a lot of helicopters in my country since cars, buses, planes and trains are more popular, however, it is my favourite. Buses and cars are slow, but they are more affordable. Trains are not so quick as the helicopter, but they are cheaper. This transport has some upsides and downsides. For instance, the most significant benefit is that this kind of transport is in the air and it can overcome money traffic jams. Though it has one important disadvantage, it is too expensive and too huge.
