How do I highway merge when my 2015 Prius C takes 11-12 seconds to even get to 50 mph?

    You must be an inexperienced driver or just one of those a**holes on the road. 0-60 times are soooo irrelevant in real-world driving conditions. I'm not sure why you're obsessed with this. If the acceleration was really a problem, you'd hear in the news that a lot of Prius C's were crashing due to failure ability to merge. But you don't.

    Actually, in numerous states, on interstates with 3 or more lanes, it is the responsibility of the far right lane traffic to yield to oncoming traffic: look at the signs on the interstate-the oncoming traffic don't even see the merge signs....

    I'd like to know which States those are. It has always been the on-coming vehicle's responsibility to yield to existing traffic when entering a freeway anywhere I have lived.

    Yea, usually the lane entering the freeway is the right lane and must yield never seen a sign saying yield to merging traffic. There are three northeastern states that I haven't racked up miles in though.

    It's just common sense too. Someone's coming up to speed while merging in front of you: calm down, ease up on the gas for a sec, we all get along.

    Not sure why everyone is thinking this is 'normal'. Something certainly seems wrong to me!

    Semantics I guess. Just never heard of the on-ramp being referred to as the right hand lane of the freeway. Sorry for the distraction.

    Rules and regs aside, a little courtesy: problem solved?

    you're misunderstanding me. when i am merging into the right lane, i am at the speed limit. i have no obligation to hit it at 80, just because everyone else is.

    Yes it IS. That's why the signs say MERGE.

    That means that BOTH streams of traffic have equal rights to the continuing lane.

    And a tiny bit of cooperation will prevent a LOT of slow down.

    You could have a plugged catalytic converter. If your exhaust get a restriction in it your car won't accelerate. There are some test to test for it your Toyota dealer needs to check it out. The simple test is to remove the O2 sensor and drive the car and see if that makes any difference but there are other ways to do it too.

    I don't think anyone mentioned the weight question. I'm not accusing you of obesity :D, but the c is a small, low powered car and is more affected by weight than other cars. Something's wrong, though, if it's accelerating that slowly.

    As for Eco vs Pwr modes, WOT is WOT no matter what throttle map you use. You floor it, it puts out as much power as it can regardless of the mode. Modes only affect partial throttle performance. We have lots of threads here about that. Some even have drawings of the throttle maps.

    Then this must vary by state. Your statement is quite false for both states in which I have been licensed to drive, where the oncoming traffic must yield to the traffic already on the highway.

    Cooperation is nice, but the legal obligations are not equal.

    • Yielding. When you’re attempting to merge onto a busy highway and the through traffic is not allowing you over, you must yield to them. Virginia law states that “No person shall stop a vehicle in such manner as to impede or render dangerous the use of the highway by others, except in the case of an emergency, an accident, or a mechanical breakdown.” Therefore, you cannot force through traffic to stop on your behalf. In addition to the law, merging traffic is better able than through traffic to slow down and wait safely, since the traffic behind them will also be slow. Through traffic is surrounded by high-speed vehicles, and if they’re forced to suddenly stop, the risk of getting rear-ended is much higher. So, slow down and yield to through traffic for both your sakes.
    • Right of Way. According to the Virginia Department of Transportation, traffic that is already on the highway has the right of way over traffic merging onto the highway. Therefore, when you’re attempting to get off the highway at the same time as another driver is attempting to get on, he should yield to you. As with most merging situations, this also depends on timing and how much space is allowed for each merger.
    And I'm done with this thread.

    triple a has mentioned that it is easier for a driver in the right lane of a highway to see and yield to cars coming off the on ramp, than it is for drivers coming onto the highway to see to the left and behind for cars in the right lane. i have always found that to be the case, but don't know if any legislation has been proposed or passed anywhere.

    Op here, thanks so much for the help! I went on the highway today to try to record me as I accelerated between 50 and 60. I talked to my recorder on my phone as I hit the speed points and then later looked at the time stamp. What we're looking at here is an average of 5 seconds from 50 to 60 on flat ground, and 10 seconds from 50 to 60 when there is a slight uphill incline, the normal kind you'd find on any California freeway, no San Fransisco or coastal mountain type ones. I'm talking San Jose, silicon valley. I that would put me at 0-60 in 21 seconds. I think I bought a golf cart, lol

    what speed do you hit as you're starting to merge?

    And if I am not going uphill, probably like 0-60 in 14-15 seconds if completely flat ground.
