1. It is a long-proven fact that power windows are not a positive feature, nor are they safer, better, or even as good as, manual windows. They guarantee you will be trapped inside and drown if you ever find yourself in a submerged car, or burn if you are in a wreck where the power to them is cut. Any of you who have ever been in such a situation already know this. As for the rest, I hope you never have to learn. Also, nowadays they are just another cheaply made system with plastic parts and Chinese motors that are guaranteed to cost you money down the road to repair.
2. Power door locks also have little to no benefit in most cases as they are implemented these days, and present their own brand of danger. They can and will trap you either outside or inside a car in a malfunction. They can actually make a vehicle easier to steal. And they are another cheaply made and overly complex system to break and be ridiculously expensive to repair.
3. The idea that the automatic transmission is better is another myth, the easiest of all to dispel. They are much heavier, more complex, more expensive, less reliable, and less long lasting. An automatic transmission uses 20% of the engine's output just to operate it, while a manual transmission uses 5% or less. Manual transmissions are easier to operate, simpler, offer absolute driveline control in icy conditions. Driven properly, a manual transmission will outlive the rest of the car, and provide better fuel economy.
4. The older you get, the more you will come to understand that your Dad was wiser than you thought. If you live long enough, that is, and are never trapped in a submerged or burning car by your seat belt, window, or door lock. Darwin's Law, however beneficial it may be, is kind of two faced. On the one hand, it prevents a lot of dissention from ever being heard, thus handicapping true progress. Dead men tell no tales. On the other, it promotes it by demonstration, showing us what works and what doesn't. Those who choose to ignore it have a fair chance of becoming a statistic of it. Only time will tell on which side you fall.
