This thesis examines the accuracy of human estimates of the speed of approaching vehicles using exterior rearview mirrors. The study was conducted in real-world traffic conditions with 20 participants, who made a total of 1,800 estimates. The results showed that neither the type nor the size of the mirror has a statistically significant effect on accuracy. On the contrary, the prevailing tendency was to overestimate vehicle speeds. The human factor is crucial. Its analysis refuted the assumptions on which earlier literature was based. Women, older adults (ages 50–62), and occasional drivers do not make fewer errors, but their errors are symmetrically distributed, resulting in a more accurate median estimate. Conversely, men, younger people, and frequent drivers exhibit a systematic tendency to overestimate speed. People dangerously underestimate the speed of vehicles traveling at 51–60 km/h. Perception of speed thus depends primarily on the individual and traffic dynamics, not on mirror distortion.

Process of defence
Student nejprve prezentoval výsledky, kterých dosáhl v rámci své práce. Komise se poté seznámila s hodnocením vedoucího a posudkem oponenta práce. Student následně odpověděl na otázky oponenta a na další otázky přítomných členů komise: 1. Co myslíte pojmem experimentální měření? 2. Zvažoval jste využití eye-trackingu pro realizovaná měření? 3. Jak se vytváří graf četnosti? Komise se na základě posudku oponenta, hodnocení vedoucího, přednesené prezentace a odpovědí studenta na položené otázky rozhodla práci hodnotit stupněm B
