I agree that these mats are sharp, but I feel like they were made for owners living in a warm climate. I live in Chicago near WeatherTech HQ and have been using their mats for many years with outstanding results. My issue with Tesla's OEM interior mats (made by WeatherTech) are the lack of a side wall and failure to cover the area where your left foot rests. For those of us in cold climates we have to deal with lots of salt and snow often carrying dirt and debris. These mats will catch some of the mess, but the rest can get stuck beneath ruining the cloth carpet.
I called WeatherTech 2 weeks ago to ask about all-weather interior mats for the Model 3 and they said they were 4-6 weeks out at the time. Haven't checked back since.
Based on your location in California I'm sure these will work fine and look cleaner/better than the mats I'm describing (pic below from Model S).
