Three things worth paying attention to this week, in rough order of how much they'll affect the average Tesla owner.

2026.8 Shows You Who's Driving, Right Now

If you share a Tesla with someone, you know the routine: get in, adjust everything back to where you like it, wonder who left the climate at 78 degrees. Tesla's 2026.8 update doesn't fix the adjustment part, but it does tell you whose fault it is. Under Security & Drivers in the app, you can see which driver profile is currently active in real time. When the car is parked or asleep, it shows the last active profile.

You need 2026.8 on the vehicle and the latest app version, both. Worth checking before you wonder why nothing shows up.

Driver profiles already handle a lot: seat position, mirrors, steering wheel height, climate settings, navigation favorites, media preferences. They can link to a specific phone key for automatic activation and support PIN protection. Restricted profiles for teen drivers can cap speed or limit features.

The visibility feature is most useful in exactly two situations. One: you have a teenager with a restricted profile and you want to confirm they're actually using it. Two: two adults share one car and accountability for the seat position has become a recurring argument. Both are real use cases.

Available on all models, including the legacy Model S and Model X. (Both are being phased out later in 2026, but still getting software updates in the meantime.)

Kissimmee, Florida Now Has the East Coast's First True V4 Supercharger

I want to flag the word "true" here, because it matters. Most of the V4 Superchargers that have gone up are running legacy V3 power cabinets inside. That caps them at 250-325 kW regardless of what the hardware outside looks like. The new station in Kissimmee (near Orlando) is different. It runs a 1.2 MW V4 cabinet across all 8 stalls and can actually hit 500 kW per stall.

That puts Kissimmee in a group of four stations in the country that can genuinely deliver 500 kW. It's the first on the East Coast.

The V4 cabinet supports battery voltages up to 1,000V, double the 500V ceiling of V3 systems. And the deployment cost is reportedly under $40,000 per stall, which is the number that matters for how fast Tesla can roll this out at scale.

Pricing: $0.40/kWh peak (8am to midnight), $0.20/kWh off-peak. Non-Tesla EVs can plug in directly via NACS at $0.56/$0.28 peak/off-peak.

For most Model 3 and Model Y owners, the jump from 250 kW to 500 kW doesn't move the needle much because their cars aren't rated for that power anyway. The Cybertruck is the primary beneficiary here. If you're running a Cybertruck through Florida, this is the stop worth building your route around.

The Tesla Semi Numbers Are Holding Up

Tesla's Semi Pilot Program, running a few hundred units, has accumulated 13.5 million miles total. One unit alone has crossed 440,000 miles. Uptime across the fleet sits at 95 percent. When something does break down, 80 percent of units are resolved and back to the customer within 24 hours, half of those in under an hour.

The redesigned Semi is about 1,000 pounds lighter than the previous version and 7 percent more aerodynamic, landing at roughly 0.4 drag coefficient. It uses fully electric steering assist, Cybertruck actuators, 48-volt architecture, and 4680 battery cells rated for 1 million miles.

High-volume production and deliveries are planned for 2026. The pilot data is genuinely encouraging. Whether production actually scales on schedule is the question I'd want answered before getting too excited about any of those numbers.
