A good sign is that Supergirl filming has ended and it is now in post-productions; editing, visual effects, etc. Such an extended period improves the odds it'll be a quality production. The cast is good, so we're down to the script and direction.
Highend Mercs and BMWs might have had it but a base model VW Golf or Honda Civic won't have it even today.
But I do agree, keyless entry isn't anything new, it's just artificially expensive.
