To be honest, that is one of the most infuriating issues with them but I don't know if they're more unreliable. TBH, I didn't think there was much difference between the Streetlite and the e200. However, there is no comparison between a Streetlite and MMCs
They seem reasonably reliable, but very rattly inside - the priorities seemed to be mainly about fuel efficiency with the passenger "ride" very distant (compared to a B7RLE, say, which felt much more like a proper bus rather than bouncing along in a milk float)
Sad but understandable that bus companies are more focussed on saving money by lower fuel bills than giving passengers a decent ride
Agreed. This is highly annoying on most Streetlites I've used. Incredible that it's never been sorted out.
Such a frustratingly "small" thing, in the grand scheme of things, if you are paying a six figure sum for a vehicle, but I guess that the bus company doesn't realise/focus on this aspect, as it's not something that particularly affects bus staff (the driver won't be able to hear it, from their seat at the front, the engineers etc won't worry about it) - but it makes the ride for passengers annoying and makes the vehicles seem like even a fairly smooth road surface is like off-road rally car driving!
