410.24Watch out for the roadworks on the Seven Bridge!\IOSG::MITCHELLElaineMon Sep 24 1990 17:1212
    
    Over the last weekend I've done over 300 miles of nightime M4 driving,
    (Pembrey race circuit and back!), plus quite a lot of recent travel, also 
    in the dark, on the M1, and M25. (from Mallory and Snetterton).
    As I'm limited to 50-60mph, a large amount of the traffic is travelling 
    faster than me, so I get to see lights approaching from behind, and then 
    the tail lights wizzing off into the distance. What is seeming to to be
    an increasing trend is for people to put their lights on full-beam, and
    foot to the floor in the outside lane! - the 'move over I'm coming through'
    attitude. The heavier the traffic, the greater the percentage of these 
    inconsiderate individuals. Has anyone else noticed this, or is everyone
    else travelling fast enough not to be bothered by these people? :-)
410.25Maybe a bright dip-beam?UKCSSE::RDAVIESLive long and prosperMon Sep 24 1990 17:4318

    It could be that you are on the nearside of the cars overtaking you,
    and the dip beam pattern these days is 
    
              \              \
                \               \
                  \               \
                    --------------  ------------
    With a strong beam angled left to light up the kerb. Unfortunately
    there isn't a kerb, there's you in the 'slow' lane (please, no one start
    ratholing on the term 'slow' lane). Thus you get caught in this bright
    angled beam.

410.26Or just badly adjustedMAMTS2::63654::NAYLORPP53546A N2433040 GM4GNJ IAMP and barMon Sep 24 1990 19:2916
One of the most common problems with all cars is badly adjusted lights.  A lot
of cars have dipped beams which dazzle more than if they are on high!  My Volvo
was notorious for having to re-set the beams whenever I had a load in the boot
because tha back sagged so much under any decent load (even when brand new) that
it threw the dip beams up into oncoming traffic.  (I later set them for a
compromise - lower dipped than usual, so they didn't dazzle with moderate loads)

The situation here in the US is even worse than the UK as most cars have that
typical soft suspension designed to ride the potholes without jolting the
driver into sensibility.  On the other hand, the Alfa is VERY low on the road
by comparison ...... and Chevvy trucks are a tailgating nightmare for me!

The dipped beam pattern theory is fine (.25), but bad adjustments and bad, or
inconsiderate, driving habits are also very likely.

410.27All returning from a fun weekend in Wales!IOSG::MITCHELLElaineMon Sep 24 1990 19:356
    
    I'm not sure it is just the dim/dip  - I'm sitting quite high up in the
    Landy. Also, surely it would be most cars which would be 'blinding', not
    just some of them, and not just the ones which seem to be going the
    fastest! I suppose it could be loading, since we were heading back
    towards the SE from Wales after a weekend.
410.28OVAL::GUEST_NNowhere at all....Mon Sep 24 1990 19:5111
    
    Same here.
    
    Last night on the A3 a citroen came up behind with full beam on.  He
    was only doing 5 mph more so he took a long time to catch up.  I
    turned my rear fog lights on and off but it made no difference.
    
    When he went past i sat on his tail for a mile or two flashing him
    repeatedly.  He then got the message and went back to dipped.
