Well of course it's a different system - I'm sure Nissan has a patent on their system since they were the first to bring it to market back in 2013 and have been improving it ever since. It's really semantics you're arguing here - the bottom line is that Nissan has had a steer-by-wire system since 2013. There is no arguing against this simple fact and only a fanboy would argue otherwise.
Car lovers will howl, but most customers won’t notice or care. That's good for Infiniti.

Nissan introduced the second generation DAS (Direct Adaptive Steering) in 2017, three years after introducing this new technology in 2013 in the 2015 model year (September 2013). DAS is currently on it's third generation with 4th generation in progress.

Unlike Lexus - this tech has been in production models QX60/Q50 since 2013. Like Tesla, it has three redundant controllers. It is being worked on as part of the transition to autonomous driving and is fully integrated with Nissan's suite of driver safety systems.
Again, I'm not taking anything away from Tesla other than the
fact that they aren't the first to market with steer-by-wire, despite the false claims otherwise. Hopefully Tesla has done this better than anyone else - and when it comes to engineering these types of systems from the ground up - generally Tesla has the engineering talent to do so and I certainly hope this is the case with the new Tesla steer by wire in the CT.
