Yes.... but only if you are looking for that pattern.. if you wanted to add
something like "sedan" then you need to use // but the qr would speed up the
compile when using a $var in the //;
if($element =~ $lookfor) { ## works if $lookfor = qr/car/; the same as
$element =~ /car/
if($element =~ /sedan $lookfor/) { ## works faster if $lookfor = qr/car/;
than if $lookfor = "car";
