I pick all the rubbish up around my house and put it in the bin. I used to get anoyed but dont waste the energy anymore.
Throwing fag butts out of the car window: is your own smoking habit so offensive to you that you can't even keep the rubbish in the car? I may be generalising here, but it seems to me that smokers start off with chucking fag ends out of their cars and then think that they might as well chuck all of the other crap out as well. Inconsiderate people. We get loads of litter on the lanes round us - mostly drinks cans / bottles and fast food wrappers. The nearest MacDonalds is over 10 miles away! TAKE YOUR RUBBISH HOME WITH YOU!
