Big thread drift! I’ve no idea how cartographic surveyors deal with it. Engineering surveyors basically ignore it.I know nothing of surveying but how is curvature of the earth factored in?
I guess that main dealers do not use any fault finding techniques. My car went in for a service and they told me the rear washer wasn't working. £60 for a replacement pump etc. I refused and showed the technician that the pump still worked by pulling off the little jet on the wiper and operating the switch. Luckily he wasn't looking too closely but all his tools got soaked as I may have kept the switch on for too long.
On the subject of spare wheels it isn't a new thing for them to be a real pain.
The BMW z3 comes with a space saver spare so that you can get on with your journey.
Too bad if you have a passenger as the main wheel will not fit in the spare wheel holder. The only place it will go is the passenger seat.
Which would you leave on the side of the road?
Passenger or wheel?
(I only know this as a friend gave me a lift in hers)
Probably a bit easier to do it that way when boring a train-sized tunnel through a mountain rather than a skinny tube through the Earth's crust, though. Especially when the first couple of hundred metres of the job are somewhat wet.No, most are laser guided. The lasers are set up by conventional surveying, using GPS for fixing the bench mark. The latest machines are self-guiding using laser gyroscopes for azimuth.
Damn right, induction noise is the tits.Landrover do the same playing a V6 or 8 growl through the speakers......
What bugs me is all these little hot hatches and so called performance cars that blip the throttle on down shifts and make strange farting noises or make some engineered false sound as the exhaust flaps open when you floor it...
Audis and VW's with DSG boxes are a prime example although they all seem to be as bad now .....the last good sounding BMW was the 3.0 CSL with the carbon roof from about 8-10 years ago .... what all the manufacturers seem to forget is a good portion of noise from a performance engine is induction noise........
Why did a Mk2 escort BDA sound so good ? because it had twin 48's on short inlets with just a little foam to dampen the noise as it sucked air at 7500 rpm.
By fitting these devices all the manufacturers recognise that driving is as much about audible experience as the ride / feel of the vehicle and performance...... yet they think we are all going to rush and buy an EV that sounds like a milk float....
Electric parking brake. Pulling the switch up engages the brake. Pushing the switch down engages the brake. Why two positions to do the same thing? There's a convoluted method to disengage the brake but I can't remember it.
Similarly hill start assist. If you come to a halt on a slope, it engages the brake for two seconds after you take your foot off the brake, effectively encouraging you not to apply the parking brake. But it doesn't tell you whether you're on sufficient of a slope for this to happen so you could roll backwards if it's a gentle slope. Or the gap in traffic that you're waiting for might be more than two seconds after you take your foot off the brake so it disengaged and you roll backwards.
Also, to disengage the brake in normal use, you just drive off. But the manual doesn't tell you how many revs you need to make this happen so if you (try to) move off gently, the brake doesn't disengage and you stall. There's also some quirk that I haven't got to the bottom of yet which can lead to the brake not disengaging when you harshly accelerate from stationary - that's loads of fun as you find that the car revs like hell with the brakes doing their best to resist movement.
What the hell is wrong with just having a normal hand brake? Admittedly, rear wheel handbrakes were crap but front wheel handbrakes did everything they needed to do.
I would have been happy to replace my Polo with another VW a year ago until I read up on DSG boxes (over the years I've driven just about every kind of gearbox. In 1990 I realised there was no point in driving a manual when an automatic just worked. I've hated every manual hire/ courtesy car I've had since).Ahh..... the joys of adaptive gearboxes, multiple drivers and a usage case outside of the 95th percentile - enjoy!
