Motor scooter? Not recommended in Brazil. Can't say that strongly enough. Brazilian drivers simply act as if motorbikes/scooters do not exist. For example, Brazilian "moto boys" in Brazilian cities have very high accident rates, with serious physical injuries. Conditions for driving a car do not resemble N. America or Thailand. " Always looking out for dangerous situations and multiple ways out of them"? So tell me, where do you go on a one-lane-each-direction road with no shoulder when 5 cars are coming straight at you in your lane at over 100km/hr, trying to pass a car in their lane?
Good luck.
