Not true at all. Your turning radius for a given sideways acceleration
is proportional to the square of your velocity. If a driver would slow
to 15 mph to make a turn with a 12 foot lane + 5 foot shoulder (using
the full space), a bike lane that puts the cyclist 5 feet from the curb
means that the driver now has to turn with a 12 foot radius, slowing
the driver to 12.6 mph. Now suppose you are riding at 15 mph. What
do you think happens?

Tell that to the parent of an 8 year old kid injured in a traffic

It actually is enough to make a difference.

I live in California and anyone who rides a bicycle in that state or
drives a car in that state damn well should care about what the
California Vehicle Code says.
If it is better than what your state has, then get your state to
make some changes. That would be far more productive than ranting
on usenet.

The vehicle code in California and many other states contains a
provision that bicyclists riding on the roadway at less than the
normal speed of traffic must ride as far to the right as is
practicable. That means on that very wide space of yours (i.e.,
a very wide lane), you have less freedom as to where to position
your bicycle than when there is no bike lane (which you don't have
to use if going at or above the normal speed of traffic).
