E-Z Pass doesn't require you to slow down, the narrow lanes with the toll collectors walking between booths and funky traffic patterns is why they force you to slow down. Parts of the NJ Turnpike and a number of the tolls in central VA are "full speed" and do not require you to slow down at all. Even the ones that you are supposed to slow down for will read just fine at 50 mph at 2 am

New Hampshire put in highway speed tolling on I-95 a few years ago (I think either in 2009 or 2010).
