Nice to see someone got it. 
With his safety record?
I’ve always wanted to have the A/C routed in such a way that it refrigerates the cup holders (or at least two in front). Seems like an easy way to keep your soda/water-bottle/juice ice-cold without dealing with an actual cooler and ice.
Maybe this option has been offered somewhere, but I’ve never seen it.
some Chrysler vehicles have/had a cooler/warmer option in the cupholders and glove box, but I think those were using thermoelectric elelements (peltier junctions.) Also the Ford Flex offers a built-in cooler inside the second row center console, which has its own compressor and refrigeration circuit.
It’s much more common now. Hyundai, Land Rover, VW, Audi, and others have them. In most cases it’s just an AC vent into the glove box but others have fancier arrangements as mentioned above.
I think new cars should come with a place for a woman (or man) to put his/her purse. When I’m alone in the car, I put it on the passenger seat. When I have a passenger, I sometimes put it on the floor at their feet, or try to balance it on the console between the two front seats. I often wind up putting it on the floor behind the driver’s seat. But when I also have back seat passengers, that doesn’t work.
Side airbags should not be an optional item, as they are for some vehicles.
I love my new Subaru but was surprised it didn’t come with automatic headlights that turn on when it’s dark so I never need to touch them.
Then again, my father’s old Tacoma didn’t even have an intermittent setting on the wipers.
But what if I want them?
I have automatic headlights on my Mazda but don’t like them. Sometimes I want to get in the car and turn on the ignition to listen to the radio, roll up/down the windows, or whatnot without the lights coming on. It also has HID lights that aren’t supposed to be turned off and on rapidly, that in itself seems counter to the automatic wiper function.
I do however have automatic/variable speed wipers and they are pretty awesome, especially when the rain switches from drizzle to downpour and back.
I had a Ford Contour without intermittent wipers, but I was able to replace the wiper control stalk with one from a higher-trim model and that added the intermittent function.
Like laughing at strawmen? I never suggested doing away with the spare tire. It is just that many times a tire will develop a slow leak that goes undetected until the tire is flat or nearly flat. In these cases, an inexpensive 12V pump will provide a solution, particularly for someone who cannot (or does not want to) change their own tire. A perfect solution to all flat tires? Of course not, but it would solve a lot of problems that otherwise would leave a person stranded.
Of course, I suspect you are aware that every car is equipped with a battery charger, and you don’t hear people saying such things, so I guess you’d lose your money.
There are problems with the alternator charging circuit, however. One, the field windings must have some voltage or the alternator will not produce any current. Two, the engine must be running, which is the whole problem in the first place. Three, with a severely discharged battery, the current load on the alternator can actually be high enough to damage it or the voltage regulator (aka, battery charging circuit).
Sure, a “built-in” battery charger you could plug an extension cord into isn’t going to eliminate all problems, but it would help a lot. As there is already the circuitry on the vehicle to charge the battery, all that would be needed is a cheap transformer, about the size of a cell phone charger, so that a 110V external voltage could charge the battery. Heck, the rectifier and voltage limiter electronics are already on the vehicle!
You guys have listed a lot of reasons (excuses) for why these items are not included in a new car. Of course, they are all irrelevant to my OP as the fact that new cars do not come equipped with these items is really all the proof needed that those who make such decisions have decided not to include them. The reasons for those decisions does not change my opinion that a lot of people would be helped if these items were included. The cost is truly trivial.
I’m having trouble visualizing how this is supposed to work. the rectifier stack is built into the alternator, between the stator and the output lug. what would it have to do with an external charger?
Every new car already has a tire pressure monitoring system so a slow leak like you describe would be discovered with plenty of time to air up the tire.
Any additional equipment has to be warrantied. It’s also going to add weight, which will effect fuel economy. For something used so infrequently, it’s not worth it to the OEM.
Maybe he meant they should be required, not optional?
Where do you even attach a trickle charger? To the battery? I’ve seen some that attach to the 12V outlets but every manual says running current into the outlets is a Bad Thing.
Not necessarily. Most tire pressure monitoring systems don’t warn you until there is significant pressure loss. Otherwise they’d be flashing every morning because your tires were cold.
Anyway, my list is seats and a steering wheel. Go fill up the options list if you want a bunch of shit in your car and stop bothering those of us who don’t. 
Leather seats in Florida? Seriously? Are you new here?
a) And that tire pressure monitoring system must cost much less than a $10 electric pump, since it costing $10 seems to be the main reason for it being a bad idea to have one in your car.
b) If your tire pressure monitoring system tells you that you have a low tire, you could easily pump it up if you had a little tire pump in your trunk.
n.b. TPMS is legally required on all new cars since 2008.
Most folks I know would just call AAA. They do that for changing a tire, or running out of gas, or any other problem. They don’t want or need a tire pump.
Maybe every car should have small pumps on every hub that constantly feed air into the tires, venting the excess. That way, like the Duck, you could adjust your air pressure on the fly (which there is typically not a great need for, but every now and then, there is).
