I disagree with this view. One has to look at Mathematics in the right light. Only then one can discover the joy of Mathematics.
Consider, for instance - traffic rules. Very practical, you would agree. However, very few people appreciate the disadvantages of zig-zag movement.
Let us consider it in the light of two well known mathematical axioms.
1. Two sides of a triangle are greater than the third side
It is a very well known mathematical axiom that two sides of a triangle are always greater than the third side.We can use that axiom to show how travelling in a straight line is a better option than travelling zig-zag. Going by the axiom,
CB + BA > CA
A vehicle travelling CB and then BA would travel more and hence consume more fuel than a vehicle going by CA.
Travelling in a zig-zag fashion is not economically viable.
2. Parallel lines never intersect
A vehicle travelling in a zig-zag fashion would have a greater probability of colliding with other vehicles than vehicles travelling in parallel lines.
That is what is lane driving. Vehicles drive in their respective lanes - in parallel paths. That prevents collision.
What would otherwise seem not very practical at once appears to be plain common-sense because of Mathematics.
Know of any other real life applications of Mathematics? Do let me know. You may leave your suggestions as comments to this post.

The first one can also be shown by the simple mathematical axiom that the shortest path between two points is along the line joining them. You use in everything from electrical to computer networks.
Yes, there are a whole lot of mathematical applications - as you'll learn in semesters to come. Will think about it when I'm less sleepy and get back to you here.
@Ibanov, Sir Rekaf: Yup, you can look at it that way too.
One can think of umpteen applications in Engineering/Applied Physics. However, the point is - there are some straightforward applications that are never taught in the textbook. One has to think of them. :)
