Wankers use all forms of transport.
I was amazed at the behaviour with water bottles on a local half marathon on Wimbledon Common earlier this year. People would grab a bottle at one of the water stations and then chuck it on the ground 30 seconds later despite there being 3 sets of dedicated bins to throw them in at intervals after each water station.
Luckily the organisers had expected some people to be wankers and their staff were there to clear up after the last runners were through.

Either way, there's no excuse.
