How did Vitézy catch speeders without a speed camera?

David Vitézy reported on Facebook that an average speed of 214 km/h was recorded on the M6 highway during a speed test conducted by Magyar Közút. This test covered three long sections of the highway, revealing surprising data about speeding violations. The Ministry of Transport's initiative is notable as average speed measurement is not officially implemented in Hungary. The results showed that over 17% of cars exceeded an average speed of 145 km/h, with nearly 6% surpassing 156 km/h. The highest recorded average speed was 213.55 km/h, and even a vehicle with a trailer reached an average of 134 km/h. This raises questions about the effectiveness of speed monitoring without police involvement.
