...The new partitions took some time to get right. New York City Transit's
assistant chief of bus training Wayne Galante tells NY1 that it took so long
because, "there was no shield available that could resist being cut by a knife,
was glare free and not too confining for drivers." But now they've found their
Goldilocks glass the partitions—which come in three types and cost between
$1,800 to $3,800 each— are getting installed bit by bit.

Transit officials say 121 buses have them now, with 300 expected to have them
by the end of the year. By March the MTA hopes to have them in 500 buses,
especially on "high assault routes" in Brooklyn, the Bronx and Upper Manhattan.
In addition the MTA has installed 207 bus cameras. 1,150 should be installed by
next year...


They've been in London for years, they have. But I don't know that they
are made of any particular type of plastic.
