Why not? How it will happen is when fully autonomous controls have been mandatory equipment on new vehicles long enough to cycle non-autonomous vehicles off the road sufficiently to allow full autonomy to happen.

If the lapper is a fast car that had bad luck, or some other reason, to be lapped then they should be given the chance to fight to get unlapped. If they’re not gaining ground on the leader and we’re talking about holding up 2nd and back and preventing those racers from taking the fight to the leader, then they should…

Well, it can only happen when the vast majority of cars on the road are fully autonomous and 100% capable of dealing with dumb cars and drivers. That means we’re talking 15+ years after full autonomy is a mandated feature on every car sold from the most basic transportation like a Toyota Yaris and up and don’t forget…

Did I ever say full autonomy will happen?  No, I just offered my thoughts on how I see things working out if it does happen.  How do you implement full autonomy until all cars that are not capable of it are off the road?  I’m 44, I doubt I see it in my lifetime.  

Just to be clear, I never said full autonomy will happen, just offered my thoughts on how it will go if it does happen. 

This. By the time we get to full autonomy, it’ll be a mix of public transportation and ride hailing services. I can see a system where you have a subscription for your commute to work and then on-demand services for 1 off scenarios.  

You’re not moving the air faster at low RPM because you have 4 valves instead of 2. CFM is CFM regardless if it’s going through 1 port/valve or 2. The further from peak flow rates, the less velocity you have. Where is your desired peak flow rate? Over 6 or 7k? Then you do want DOHC 4 valve. I’ve never denied that’s…

Yeah, and if you want to turn some RPM, you’re better off with 4 instead of 2.  But if you’re not looking to build a revver, then keep an open mind.

So I get an extra 1.2L for the same weight? Cool! And the Vette isn’t a supercar, it’s “America’s sports car”. The Ford GT is a supercar. Only place I’ll see one is on the dealer floor (local one has a Gen 2 behind ropes) but I could realistically buy a C8 today and might actually do that in 2-3 years once dealers…

Large port volumes with big flow numbers wind up with lower intake velocities for a given RPM. Low intake velocities inhibit cylinder fill. Air has mass and doesn’t instantaneously fill the cylinder when the valve opens. That’s part of why highly “efficient” engines don’t make much torque down low but then scream up…

The issue with the Fiero was the handling on the early years was sketchy. IIRC, they cut corners in the suspension design. By the time it was updated, the reputation for sketchy handling was too much to overcome. I remember an AutoWeek article when it was cancelled talking specifically about how it was finally fixed ju…

Yes, a 4 valve head flows more air than a 2 valve head for a given bore size. The issue is that extra flow doesn’t help until you’re at the high end of the power curve and will hurt at the low end. If you’re chasing absolute power relative to displacement, then a 4 valve DOHC engine is the best option, but you have to…

Unless you’re turning RPMs into the 8k range, you don’t need OHC. If you’re building an engine in a V configuration and don’t need that high rpm ceiling, why not go with a pushrod design? The smaller and lighter design gives you more displacement to work with to tailor the power delivery exactly how you want.

The X1/9 was total garbage. My dad bought 1, had it for 2 months and it spent more time in the shop than at home. Perfect example of “Fix It Again Tony”. The Fiero was flawed and by the time GM got it figured out, the reputation was too much to overcome. 

3rd/Neutral: Yes, the new Vette will sell well. I see way too much interest, dare I say excitement, from people who can afford one to think it will be a dud. You’ll still get the 60 something buyer who GM has relied on plus the 40 and 50 something who would normally be looking at something from Europe.  Probably even…

Well, the switch to mid engine (mid rear for the pedantic) is huge news! Why should there only be 2 or 3 articles?

Yikes!  That’s a rough day.  Hope the compensation is worth it.  

When you put the engine behind the driver and put 60% of the weight over the rear tires, you can drop 0-60 times without adding any power.  0-60 is about traction when you’re dealing with 400+HP

Geez, what kind of commute and/or working hours do you have? I’m fortunate to have a sub 20 minute commute, so my 10 hour work day doesn’t turn into something too much longer.

My alarm goes off at 5:30. I go to bed by 11 at the latest. The nights I stay up later catch up to me well before quitting time.
