    Both bores of the Port Tunnel now have a chevron about every 100m in each lane. I'm assuming this is for some sort of guide to get vehicles to keep their distance whilst driving in the tunnel.

    They are very badly finished lumpy chevrons, that make your tyres go "ba-dong" as they cross over them.

    Would that not be the point?

    The system is used in UK. Think I remember driving on it on the M56 nr Liverpool. It definitely helps people keep their distance - something that a lot of drivers on the M1 in the mornings could do with learning.

    No. It's supposed to be an optical input, not haptic. They fecked it up, is all.

    In Cavan there was a great fire / Judge McCarthy was sent to inquire / It would be a shame / If the nuns were to blame / So it had to be caused by a wire.
