inventions

I have some problems that seem to plague me no matter what. Though they are small, unimportant, and stupid, they still irk me enough to dedicate an entire post about them! Whenever one of these things happen to me, I think, "wouldn't it be nice if someone invented something to save me from this hell?" So now, I will attempt to throw some ideas out there for the next new innovator.
The first issue I have is with traffic. Yeah yeah, mass transit and the whole rail system that is being dissected throughly will solve a little of the traffic problem we have here. But what I really hate is getting in the slow lane. Maybe it's because I'm a teenager. Maybe it's because I'm just impatient (probably goes hand in hand with being a teenager). But I'd like to get in the most effecient lane, thank you very much. It's supposed to be the outside lane, but does that always happen? No. So I go into the next lane that SEEMS like there are fewer cars, and that it's moving along quite nicely. But, nooooo, the traffic gods just want to see me suffer. So as soon as I change lanes the one I was formerly in miraculously becomes speedy and the cars fly by at a satisfactory rate. Meanwhile, the lane that I am currently in, the one that appeared to be effecient suddenly moves at a snail's pace. Am I bad luck?!?! This happens to me frequently. WHenever I seize the opportunity to change lanes in hopes of getting into the faster one, it always becomes slower. I guess I should just be more patient because the lanes I'm in tend to speed up eventually. But because I am a bit impatient, and I don't think that I'll change all that much in the near future, I propose to invent a device that indicates which lane is fastest. It senses the # of cars up ahead in each lane and if there are any SLOW CAUTIOUS SAFE DRIVERS THAT WE SHOULD ALL BE LIKE BUT MOST PEOPLE AREN'T and if there are any accidents and the average speed of each car in the lane. Some supercalculator that would be, huh.
The second invention I propose is a sensor that you can stick on to anything so you won't lose it. I don't know how many times this would come in handy in my life. It'll probably save my butt more times than I can count. For example, I currently do not know the location of my ID card. I need it for food. Where art thou, ID card? If I buy another one, it'll be my third of the year, meaning I would've spent a whopping $30 on something that shouldn't be lost in the first place. With my invention, a little sensor that comes with a tracking device, I'd never lose it again! It'd be like one of those dot things that the CIA secretly put on people to keep track of them. ANd then I'd have a small little screen like the size of a gameboy or something and I'd be able to find it. It would beep all crazy-like if I pushed the "seek item" button, and it'd be a little blinking dot on the screen yahhhhhhh! The screen would sense my location (using infared or some other sensor thing that I would put on myself) and I'd be able to see my position relative to the missing item. I really need this device. Desperately.
I realize, of course, that these inventions probably won't logically work, and even if they did, hardly anyone would buy them (except me). ON the other hand, technology is steadily advancing! But alas, I can dream that maybe one day my petty beefs with various events in life will vanish!
