You could have downloaded aDriverTest 3.0 for Mac from our software library for free. The application lies within Games, more precisely Action. The actual developer of this free software for Mac is Andrea Cantadori.
From the developer:
aDriverTest...Ever wandered how much alcohol influences driver's reaction time? aDriverTest is the easy, reliable, answer.
A severe policeman is challenging you: will you dare to test your reflexes? Ten traffic lights will come out at random: shake your iPhone to brake! But don't shake in advance: the Bad Guy will fine you...
The more it takes you to shake (brake), the more the beer level increases!
