"We have a lot of Ute drivers (pick-up trucks) and they are mostly driven by tradies (tradesmen - wood spoilers, plumbers, electricians, air con fitters) who take great pleasure in trying to run you off the road, block you, cut you up, throw things at you....Riding on the roads here in Victoria can be hard "
i get that, had things thrown, abuse and was hit over the head with a rolled up news paper from a moving vehicle it felt like a base ball bat!
i don't use the neck rest now unless i stop or am going very slowly up a long hill with all the camping gear on, i did to start with on some of the steeper cambers just to get in to the habit of relaxing back, just going floppy in the seat helped me.
i had to mess about with the tension on the seat to get it spot on for me, i am not 100% on what your seat is like but i think it has one long bungee cord ruining through it, you could look at using three sorter piece's so you could have different tension at different parts of the seat, some people put pipe lagging on the down tubes to fine tune there seat.
look at this.

have had to make a ventasit cover for the handbike with lumbar support and slightly raised side bits as the seat was not the right shape for me.
i find riding in the edge encourages bad over taking a good 1.5m out about where the inside set of car/ bogan limo tyres would be, this also should be the cleanest bit of the road, any thing on the back that flaps about making you look bigger.
i use all 12v car lights on my trike the led strip that comes out of brake lights on the back and led fog/spot lights on the front, very bright and will run for 5hrs on a 1.2ahr battery.
the big bouncy things, mmm other than whistling the theme to Skippy i cant help you there, but apparently if you have a mechanical problem one will rush of and get help.

always have a look in there pockets as most of them have stolen diamonds gold ect in them.
