Well.... I don't know what makes u proud of driving at 140-160 and beating the radars... in a way u r violating traffic rules.

As said earlier there's no complusion to look at those timers they are just for added assitance...

FYI... shortly the advanced radars installed in qatar would be similar to those in Dubai, which would capture continious recording of cars and compare the time taken between succesive radars to know if u have crossed above speed limit.... i think that bad new's for u ...
