Im sure in many countries these kind of deliveries are becoming more and more popular as it is convenient and people nowadays like to have things delivered, including food.
I live in China and here on the streets theres delivery guys everywhere, on everycorner theres a few of them. Not sure whether it is safer or not, but they use electric bikes here to deliver the food. probably more ecofriendly but still dangerous on the road as there are no separate roads for cars and bikes. Be safe whether your driving a car, a bike or walking!. Cheers
