Rain proof F1 tracks

Since I started watching F1 races with my boyfriend I always had this question and no one has yet to give me a convincing answer. Why can't the tracks be covered with roofs to make them rain proof? They can be made of glass or transparent plastic material to facilitate TV broadcasting from all angles and heights. It can help reduce accidents, allow the cars to run the fastest they can on dry surface and the races don't have to be suspended when the tracks are flooded with torrential rain. People tell me it's difficult to construct or the cost is too high. hey guys, to start with F1 is a multi-billion dollar industry and second what's so difficult engineering-wise about setting up a roof?? It's not building the Parthenon or the Pyramids. It must be something else. Can anyone here answer this?

Just a thought..

I always have these great ideas to freak people out and amuse myself, but I don't ever actually have the balls to do it.

So anyways...this morning I was doing my weekend jog w/ my friend (jogged 18 min then 5.5, woohoo!) and we had several cars of guys slow down to yell things out the window at us. This is not uncommon, but its just so weird. Because seriously? This is when you want to yell out at a girl? When she's sweaty and gross and up at the ass crack of dawn (or like, 10am, whatevs) to jog? But you know they aren't really hitting on you. They're bored and trying to be funny.

So that got me thinking... what if we could find a way to just freak them out. For example... car slows down at stop sign and yells out typical "shake it baby WOO" and instead of ignoring them or giving them dirty looks, we smile? And make a bee-line for the car and be like "omg you guys are SOOOO cute, so you want our numbers? omg we should TOTALLY go out tonight" etc etc. It might just get them to stop yelling out to random girls. it'd be a public service really. Just a thought.
