Well, for me I don't specifically have a brand of car which I think is the safest or trusted brand. I can go for almost any brand of car as long as it attracts me and I find it having all the qualities I require in a car.
To answer your question, i think it's of importance that the general public's choice in a particular car brand should have be put into consideration. In saying so, my answer would probably be Mercedes Benz, Toyota and Honda cars as they seem to be more of them on the streets.
These three mentioned car brands above are the most common and used cars in my country regardless of their models. You can literally count 4 Mercedes, 2 Toyotas and 3 Hondas out of 10 cars in a traffic. I think they are the most preferred basically because they're affordable and the parts easy to come by which in my opinion are factors needed to be put into consideration before purchasing a car in any place, region or country. And besides, almost every auto repair shops here are acquainted with these three products. These are probably the main reasons why people here prefer theses three products. I for one will go for any of the three if I want to be cot efficient.
