The streets of Bangkok are busy. The law of the strongest applies here and it does not favour pedestrians. Basically you just have to cross the street and hope for the best. The same applies to Tuk Tuks, small basically self made Taxis. There is a saying in Bangkok: “If you aren’t able to pass your driving exam, you drive Tuk Tuk!”. Still it’s part of the experience and definitely a nice way to get to know the city. Usually you have a Tuk Tuk for a whole day and it brings you to the major sights, just be careful if it seems to cheap (20 Bat), because then some drivers like to bring you to suit shops first to cash in some commission.
