For many reasons Tesla has put EU Signature holders behind approximately 15000 regular American customers. This way of prioritizing has been suboptimal for the EU Sig holders. Tesla has by this move kept the loan from the Sig holders 1 year longer than the intention was.
So, by this argument, all US and EU production should have been delayed until the RHD (UK, HK, AU, etc) signatures were delivered, while the factory sits idle?
I don't believe that is what Tesla promised. They promised that Signature reservation holders in each particular market would get their cars earlier than production reservation holders in the same market. So, Norwegian sigs before Norwegian production, Swiss sigs before Swiss production, Hong Kong sigs before Hong Kong production. And, roadster friends & family before production.
From what I read, the launch in US didn't go exactly that way in all cases, but in general that is how it proceeded. In particular, the related promise that 85kWh would get their cars before 60kWh before 40kWh and delays with some paint colours and other options, really messed up the order. Hopefully for Europe the supply chain has stabilised now and things will be fairer.
The real issue is that with a production rate of more than 400 cars a week, they have the capacity to produce the signatures very quickly. The time frame between the signatures and production vehicles will be very small. But, what is Tesla supposed to do? Pointlessly delay production vehicles by months just to make the signature holders feel better?
I suspect that the bottleneck is not going to be production constraints, but rather delivery constraints. Certainly, I don't see how the small Hong Kong team is going to deliver 300+ cars in a short period of time (when the same team spread 50+ roadster deliveries over two years).
Secondly, we see the delivery process in Norway (first of the EU deliveries) starting up slowly. They seem to have a priority process beyond this topic, apart from the fact that the regular cars seems to scheduled for delivery only days after the EU Sig cars. Thus again cancelling the argument of early delivery of cars to the Sig holders.
Thirdly, EU Sig holders has an agreement that make them pay approximately $5000 more for their cars than a similarly configured regular Model S.
I will argue that Tesla should admit that they have not kept their part of the agreement with the EU Signature holders, and refund the price differential. By doing this, the EU Sig holders have contributed in funding Tesla, and for this they get their Signature cars. Tesla on their hand acknowledge the late delivery and align the Signature price with identically configured cars. After all it is identical products apart from the Signature decals.
We saw the same arguments from the US signature holders a year ago. The difference being that for EU signature holders they could see the situation and history well in advance of order lock-in.
For me, the choice of signature vs production comes down to that red colour. I can't justify it (especially as I live in a small place and a 60kWh battery is more than sufficient), but I live in hope of winning the lottery to make me change my mind.
