Are road signs becoming more threatening?

Whilst travelling on the M25 and the M1 from Enfield to Buckingham this Monday, i came across the following roadsign/instruction/command/threat:

"BIN YOUR LITTER, OTHER PEOPLE DO"

The GREEN Party have obviously come across a large bag of cash to be able to pull this sort of advertising stunt!

I would also like to know who these other people are, and why on earth they have been calling up the M25 Road Maintenance Head Office to inform them that they dispose of their litter in bins.

Do they want a medal or something? 

Now the above picture is more my cup of tea.

The poor motorists continuing on the M25 are being told to drive with CAUTION whereas I am part of the lucky ones who are escaping onto the M1 and onto the not so lovely 50mph restriction zone!

How long will it be until the huge companies like Nike, L'Oreal start advertising on our motorway roadsigns?

Picture the following:

• You've been driving for an hour and a half, boredom has gotten the better of you, and you've finally reached the exit you are supposed to take, the road-sign reads, The next left for Enfield, Just Do It.
• It's early morning, you woke up late and had to rush out of the house, no breakfast, odd socks on, beard untrimmed. The only thing that could make you forget about this morning's mayhem  is a nice hot coffee at Costa at the next service station on the motorway. So when you see the road-sign "For Services, take the next exit, Because Your Worth It"...you know for a fact you'll be stopping for a sip of perfectly ground coffee beans.

Au revoir!
