Renault were working on the since before 2008 (2005 apparently), yet they only brought a product to market in 2012.
The Tesla Roadster was developed around the same time, yet deliveries started in 2008. By the time Renault got around to actually making the Zoe available to customers, Tesla had been selling the Model S for 6 months. I don't think they were taking EVs particularly seriously if they took that much longer to put out a less sophisticated product despite having vastly more resources at their disposal.
Sure, because the Tesla Roadster is half a car, and cost is no object. They literally took an existing car, and built an EV conversion kit, money be damned.
Making the first mass-market EV was going to take multiple years, no matter what. You need to engineer the entire car, at scale, and you need to hit a price-point. Tesla didn't have such an issue. I can't stress enough how much more difficult it is to make an affordable product than one where price is no object.
