The rear windshield is split, and that took some getting used to, but it doesn't actually affect visibility. It's just a bit odd at first, that's all. We have a backup camera, but it only works in reverse. Having a backup camera is pretty awesome.Congratulations. You have a third generation (2009-). I haven't driven one, so I am not familiar with any nuanced differences. Probably mostly the same car with efficiency improvements.The technique I am talking about is called hypermiling. The Prius takes up to 10 miles to get the battery full charged and everything to optimal temperature. You have probably noticed that gas mileage can take a big hit in winter. The battery doesn't charge as quickly when temperatures drop below 40 degrees. Hypermiling techniques may not yield impressive results this time of year. They will help, though.I use cruise control as often as possible. All around town. Even at 30 MPH and below. Consistent fuel flow helps to get the best gas mileage (obviously), and I feel like the car can deliver that better than my foot. So, cruise control on the highway. I find that short periods of acceleration above cruising speed allow the battery to charge quickly and gas mileage improves. Set cruise control. After a time, accelerate above that speed, and allow the vehicle to come back to cruising speed. You will notice the battery charge and current MPGs will improve. Your average may not show a difference, but it will help your current numbers. Resetting MPG at every gas refill (or sooner) helps to get a more clear idea of how these technique improve fuel consumption overall. The longer you let the average ticker run, the less current numbers will affect it. These cars love hills. The engine will shut off as the vehicle accelerates downward. You are riding for free at that point. The extra charge will more than make up for the hit you take on the incline. Accelerate slightly into the initial peak and don't hit the gas until you start to lose speed on the upwardincline. Your consumption will improve.I roll up to stops as often as possible. Anticipate them well ahead of time. As long as the wheels are moving, the battery is charging. If your foot is off then peddle, the engine will cut out (unless the battery is severely drained). Coast into that stop light or stop sign. Your consumption will improve.Prius' reclaim power during braking, using that power to charge the battery. At speeds above about 7 MPH, the Prius will use the engine to slow the car. I don't fully understand the mechanics, but this is when power is reclaimed. It is not through the actual brakes at the wheel. Emergency breaking will engage the pads, but mostly they are not used until the car is almost stopped. This is why brake pads can last 200k+ in these cars - they are hardly ever used. One less expense we need to worry about. There may be other techniques. These are the ones I use. They work well for me. Understanding how these cars operate differently than most conventional automobiles will help you develop your own habits to reduce fuel consumption.
