Wade L. Robison's Commentary on "Cutting Roadside Trees"
Whenever one acts, one is acting within a context, and the
context may make some options preferable to others when, all
things considered, it would be better to do something else
completely different. For instance, in European countries many
roadways have trees right near the road. These were often
planted, among other reasons, to form a canopy over the road,
making the road less likely to be covered with snow in the
winter and more likely to be cooler in the summer. No doubt
accidents happen there too, but the costs of lawsuits to the
European equivalent of country road commissions has not been so
great, for whatever reason, that European countries have felt
moved to remove trees for safety's sake. Indeed, even on
heavily travelled roads, the autobahn's of Germany, for
instance, trees are often planted in the center between the
double lanes of traffic in order, among other things, to
prevent traffic lights from shining into the eyes of oncoming
drivers.
In addition, though widening roadways is the accepted
procedure in this country, whenever a road becomes so heavily
travelled that the incidence of traffic accidents increases, it
is not necessarily the preferred solution if some things were
fundamentally different. More public transportation is
available elsewhere, and that can help alleviate traffic
congestion, and if Americans were willing to use such
transportation, and it were cheap and readily available, such a
solution might help. In addition, one can build other roads to
help alleviate traffic, another two-lane road taking the place
of doubling the lanes on an existing road. But such a solution
often produces new problems--other land being condemned, other
trees being cut, and so on. In addition, it is probably likely
that any state or federal aid available is tied to widening
existing roads--tied, that is, to what is the preferred
solution in this country--rather than anything innovative.
So Kevin Clearing's problem is that there are few choices
available to him given, among other things, the state of the
law in this country and the likelihood that someone, going
within the speed limit, will crash, and sue, and win a large
amount of money from the county. There are enormous
disincentives to do anything other than widen the road, and
there may be enormous incentives, in the form of support from
the state or federal government, to do that. One person cannot
change an entire system.
Clearing has been asked to come up with a solution to the
traffic problem, and he has. He has come up with one that does
not try to change those features of the situation that seem to
be causing the difficulties--whatever it is about the drivers
and the situation that has caused one fatal accident every year
and numerous other accidents, whatever is causing drivers to
drive too fast on the road, whatever is causing the increased
traffic on the road, whatever it is in the system that produces
huge amounts of money to those who are harmed in accidents and
successfully sue, and so on.
No doubt other options are available besides widening the
road--putting speed bumps in the road to slow the traffic,
putting guard rails up to keep traffic within the roadway,
increasing police patrols, and so on. Each of these options has
its advantages and disadvantages, and perhaps one of them, or
some combination of them, would succeed in making the road
safer.
The decision is ultimately a decision that must be made by
the road commission. They pressed Clearing to come up with a
solution, and they presumably must ask him to come up with some
alternative: it is not clear, that is, that he can act on his
own initiative.
If not, then he must act, if he feels impelled, as a private
citizen, and he will have to decide whether to bring before the
road commission other options he thinks might help. Deciding
that will present some problems, for he might be perceived by
the road commission as undermining the recommendation he gave
them and so undermining the commission itself. So he ought to
ask them how they want him to proceed--if he thinks he can do
anything further regarding the issue.
If he can proceed on his own initiative, or if the road
commission asks him to proceed, he ought to present the reasons
for the original solution provided--the concerns about a
lawsuit, and so on--and to present alternatives, with all their
attendant problems and benefits. Clearing ought to have
originally provided the reasons for whatever solution he thinks
is optimal, explaining clearly how he is ranking the various
values in conflict here, how, that is, he weighs safety against
the concern for the environment represented by the citizens'
arguing to save the trees. If he now thinks some other solution
may be preferable, he ought to present it, with its attendant
benefits and burdens. His obligation, that is, is to further an
informed and intelligent dialogue among the interested
parties.
It may be that out of that dialogue some alternative
solution may emerge. For instance, one easy way to ease the
problem caused by crashes is to make it harder for motorists to
hit trees, and one way to do that is not to cut down underbrush
near the road, as is the preferred option among road
commissions throughout the country, but to plant bushes that
will absorb the impact of cars, causing minimal damage to them
and to their occupants by preventing them from running into
something, like a tree, that will not give upon impact. The
road would then look far different from how most American
roadways look--not cleared verges, with a stand of trees beyond
the grass or gravel, but densely planted verges, with bushes
close to the roadway. Whether such a dense population of plant
life could be maintained in a roadway system that relies so
heavily upon salt to clean off ice and snow in the winter is
another issue, but the point is not that such planting is the
preferred solution, but that making clear the reasons for
various alternative solutions can do much to initiate an
intelligent and informed dialogue about what ought to be done,
about which values ought to be given prominence and which
solutions are more likely to preserve those values and cause
the least harm to other values at issue.
