50 years ago, almost nobody had a car. Now, every family has one, two or three cars!!!! Parking when you finish your work, or when you go everywhere is very difficult and you waste much more time sitting in your car looking for it. So, if you count the minutes that you are in your car doing this every day, in one week, in one month, in one year.... and so on, you can see that you loose more time in that thing, and maybe you could do many other interesting things in place of that. People time doesn't have price (this is an Spanish sentence!!!).
