ABS and things.

Nothing magical or godlike - just technology that can do some things better
than people who are fallible and whose physical reactions are not in the
millisecond range.

Ther will indeed be rare situations where this sort of thing may occur in the
same way that seatbelts sometimes worsen the injury in an accident but no sane
driver that I know uses this to justify not using seatbelts.

We probably have more dirt and gravel roads, proportionately, than you have
and certainly have many drivers who would disagree with this opinion.
No reasonable driver would regard ABS as a substitute for careful and skilled
driving and it cannot overcome ALL braking problems but it can and does give
a substantial advantage in many situations for most drivers and has
undoubtedly saved far more lives and prevented or alleviated many more
accidents than it has ever contributed to.

The OBC is indded a nice toy and one can play for hours but it is useful, it
can work out your anticipated range and time of arrival without distracting
you too much from concentrating on driving - even if you ARE a mental
arithmetic whiz. As far as carbs and points are concerned, the only possible
advantage they offer is simplicity, worn points must be the commonest reason
for performance fall-off or just plain dead engine and anyone who has read any
technical documentation on carburettors should understand how much compromise
is built in to those. A good engine management system automatically adjusts
both fuel and ignition timing continuously to suit the engines needs. It may be
that some of the draconian pollution legislation that you in the US suffer
under impose some restraints on performance but having had many years of
life with carbs - multiple SUs on an AC and Bentley, twin Solex on a BMW 2500
and more time than I like to remember adjusting and replacing points on
everything from a 1929 Austin 7 to the BMW2500, give me a computer to do it
anyday.
Technology shouldn't replace skills, it should augment them. Anyway enjoy
driving your BMW with or without ABS and Digital Engine Management and have
a good day with safe driving. Best Wishes to all from South Africa (with 3
Olympic Golds to cheer us up!) DaveE.
