Broken bottles are a real problem but good quality tires saves you a lot of flats. Not saying you can drive carelessly on any debris but a 30€ vs 10€ tire will be day and night. The Schwalbe Marathon Plus are the best known reference in this field. In my experience ”durable” tires from others brands are sometimes great and sometimes crap.
Also a regular bike checkup should includes tires checkup to remove the debris stuck in the rubber. Those can “move” and get you flat in the future.
