I understood perfectly what you were saying. I just disagree.

I will give you an example of where that is not a good idea. It's
within the boundaries of Milton Keynes so you may know it; it is the
roundabout on the A5 to the south of MK where it joins the southern
continuation of the V10 Brickhill Street, the A4146 to Aylesbury and
the southern continuation of the V4 Watling Street (old A5).
If you know this junction well, you will know that it is an accident
black spot. It is heavily congested in both rush hours, tidally, with
northbound traffic congested in the morning rush and southbound in the
evening. So poor lane discipline is complicated by aggressive driving
and people using hard acceleration to take advantage of gaps in
traffic.
Traffic from Aylesbury using the A4146 single carriageway splits into
two lanes on the approach. The lanes are not marked.

If turning left into the V4 Watling Street (1st exit) there is no
doubt; you should use the inside lane.
If taking the second exit onto the A5, which is still well to the left
of straight on, you should use the first lane. But some people use
the outside lane, as indeed they do if coming from Dunstable on the
A5.
If taking the third exit onto the V10 Brickhill Street, that is as
near to straight on as it gets, so you should use the inside lane. Of
course that risks conflict with drivers who are using the outside lane
and turning onto the northbound A5.
However, using the outside lane invites conflict with drivers from
Aylesbury using the left lane who are also heading for the V10, and
with drivers from V4 Watling Street heading for the southbound A5.
Similar conflicts occur when entering the roundabout from the V10
Brickhill Street, so no point listing them.
In the last two years, I have witnessed four collisions here. Two
were at the exit onto the A5 northbound, one at the exit onto the V10,
and one at the exit onto the A5 southbound. All of them caused by
people exiting the roundabout from the outside lane.
There have been numerous near misses. Only once have I seen someone
turning right using the inside lane. Obviously there are some people
who do that but it is mercifully rare, and the major risk of collision
is caused by people using the outside lane. If drivers adhered to the
recommendations shown in the Highway Code, in particular using the
left lane for going straight on, the risk of collision would be
significantly reduced.
It was as a result of experience at this junction and at one in
Aylesbury that I researched the guidance on which lane or lanes can be
used at a roundabout. I looked at the Highway Code and talked to my
cousin, a driving instructor, and a mutual friend who is a driving
test examiner. As a result of this research, I now always use the
left lane when going straight on.
