Wrong way up the sliproad

[ali4390]

I'm currently stuck on the M11 in quite long tailbacks. When coming onto the sliproad at junction 10 I witnessed not 1, 2 but 3 vehicles coming the wrong way up the sliproad, with their hazards on as though that would make it slightly less fking stupid!! I'm assuming its illegal aside as well as fking moronic?!

Does anyone here do the same when faced with traffic?
