When it comes to driving in the city we always have to face the same issue again and again. Who has not, for even once, spent hours and hours driving throughout the city to find one suitable parking spot? Indeed, usually we have to find a spot that is big enough, that is not forbidden, that is safe and in the best case that is free. The result of all of this is that, according to a survey, on an average we spend 30 minutes per week looking for a parking spot. Thus, in a lifetime we waste 2 months and a half trying desperately to find where to live our car. 
So next time you will go for a ride in the city, don't be surprised if it takes hour to find the perfect spot !
