The lines are squiggly because even if you have a tripod there will be some up and down movement of the vehicles themselves.
Do you mean you just want the lights to be point light sources, ie no lines at all?
If so, you'll need a shorter shutter speed which generally means you'll either need more light, or a lens that has a greater aperture. (Which in turn affects depth of field)
Can't do it justice here, so ...

1) Are the vehicles moving?
2) Exactly what effect do you want to achieve?

(Edit: perhaps stating theobvious!) Basically to shoot distant objects at night, you have to gather in a lot of light from far away.
This means either a long exposure time (tripod, movement - particularly of point light sources), a fast ISO film (grainy), or a lens capable of gathering a lot of light on a short exposure (expensive).
Take a look online at the difference in cost between a consumer zoom lens and a professional zoom lens for action photographers (same deal as your night shot ... capturing fast movement from afar without movement in the daytime can need a very good lens).
What kit are you shooting with? (Sorry to answer your answers with more questions!)

I found a review of your camera Michael, and this might be of some interest:
"Interestingly, the R817 never seems to select ISO 400 when it is set to ISO Auto mode, maybe an indication that you should only use ISO 400 if the lighting is really poor and you have no other option."
So, that's the digital equivalent of using a faster film (more noise in image).
In addition, as mentioned above, a remote shutter release if possible.
Also, shield from the wind.
Your camera is a standard domestic type, so I wouldn't hold up great hopes to be brutally honest.
One of these might be good, paired with a digital SLR.

Then again, it does cost ten thousand pounds. For one lens!
