My town was holding it's annual craft "event" today and there was a marked PSP unit roving around throughout the day to deal with traffic issues, miscreants, etc. It did not have the usual Federal Signals Vector lightbar but a more conventional boxy rectangular looking lo-pro LED bar, maybe a Fed Sig Legend: http://www.fedsig.com/industry_solut...ch1635_407.pdf
I've never seen our local barracks involved in testing new equipment, so I have to assume it's going to become the new standard. Also a month or so ago, a friend in Harrisburg saw one of the new Ford Taurus PIs in PSP markings, which was likely a test since it isn't generally available yet: 2012 Ford Taurus Police Interceptor Revealed!
That will be formidable, available with the 365BHP EcoBoost V6 AND four wheel drive!!
