Brushes ?? I didn't realise there were any electric cars still using brushed motors...so there's one to be avoided.“The only thing that’s gone wrong is the electric motor brushes have had to be replaced (a warning light illuminated on the dashboard), but it was done without fuss by the Renault dealer under warranty.
And it would appear that Uber are ignoring the authorities' demands to cease the experiment !!myglaren wrote:And I have just seen in The Gruniad that the Californian authorities have killed the experiment.

Uber defies demand to cease self-driving
Lets put is this way you get a very different image list if you add the term USA to a "belt and suspenders" queryIn a conference call with media on Friday, Uber's vice-president of Advanced Technologies Anthony Levandowski said Uber had "respect" for officials, but that the regulations were irrelevant to its cars.
"You don't need a belt and suspenders if you're wearing a dress," he told reporters.
In his view the permit only applies to cars that could operate "without the active physical control or monitoring of a human operator".
I think Uber have a point when they draw parallels with Tesla's 'Autopilot' function though.Gibbo2286 wrote:I think Uber will find they've met their match if they take on the California DMV.

I have the same viewpoint on drone deliveries...
Surely not a simple piece of manure I hope. I presume they will have a rural mode which will have manure-proof sensors, and they will have modelled carefully the behaviour of sheep/cows when they congregate in the middle of the road ahead.....rather like Giles' little cartoon residing in the Pickled Egg Library.bobins wrote:......And what could possibly go wrong with that concept ?

Such a mode will turn it into a completely incompetent, ignorant maniac if my experiences of rural driving are anything to go byNewcastleFalcon wrote:bobins wrote:I presume they will have a rural mode
Don't know enough about them first hand, but seems quite a logical analysis above, and for DIY Conversions offers the simplest solution.Motor: Advanced DC 203-06-4001A
The brushed series DC motor is the best overall motor for affordable road-going conversions available today. AC motors operate at high rpm that have to be stepped down, and have expensive and complex speed control systems. Brushless DC motors also require expensive controllers. Permanent magnet motors are very efficient, but only in a very narrow rpm band, and quickly lose their efficiency in the varying speeds of normal driving. Shunt and compound motors are more expensive to build and have poorer acceleration than series motors. For these reasons, the brushed series DC motor is the motor of choice.
