The "extra load" is not discernible at all. There is a buffer in the form of the battery. The alternator's output is more than enough to power the electrical system and keep the battery topped up, even on tick-over. The little red light on the dash used to come on whilst waiting in neutral. That never happens with a modern car. Far more fuel is wasted during the holdups caused by cyclists, not to mention the additional pollution. Although I didn't mention it in the previous response to the unimportant TMS320 (it's odd how he snipped that bit!), as well as the engine being far more efficient these days, as well as the alternator, batteries have improved out of all recognition. A few decades ago, you needed a new one every couple of years. A car I bought new in 2006 and disposed of in 2014 never needed a new battery and the car I bought to replace it (in 2014) has never shown the slightest sign of being any different in that respect. |

It won't be discernable to the owner. Just as the many tiny things a car manufacturer develops in the lab are not separately discernable. Just because you can't discern something does not mean it does not exist. The "extra load" is not discernible at all. There is a buffer in the form of the battery. Perpetual motion is impossible. There is a Law about it. |

[courtesy J Nugent] Alternatively: You need to quantify it before you can state it as fact. While the driver sitting behind the cyclist must use more fuel than if the cyclist was not there (and will see a peak in instantaneous consumption), it wouldn't be significant enough for the driver to notice when looking at the journey average. But there is a flaw in the argument. The bicycle user is also doing a journey. If that person was to do their journey by car instead, then two cars would be consuming and polluting. The notion falls over. ...... As a supplementary, the load of the headlamps is roughly similar to the effect on rolling resistance of 100kg of weight in the car. For instance, my previous car only came with a can of foam so when I put a wheel, jack and brace in the boot, I added something like 30kg. This would have increased rolling resistance by 3N which converts to 1 litre per 2000 miles (and is extra to the additional KE that gets dissipated through the brakes). I wouldn't be able to isolate that contribution even though I keep a spreadsheet and know it is present. |

It must have been the performance enhancing drugs talking that I took for my 40 mile bike race yesterday... an all you can eat breakfast. I completed the two stages of the race in a gruelling 3 hours 46 minutes 3.58 seconds. Give or take half an hour. It would have been faster but, in cycling tradition, we carried our old kitchens, televisions and car tyres to leave along the verges as a gift to the poor people that can't afford to move out of the countryside. this is a NG for personal bickering dog-walking anecdotes and fanatical attention to the level of fluid in screenwash bottles. He keeps telling me I'm a boring ****. So the plan is to try to send him to sleep for long enough that his little doggie has to resort to desperation to get something to eat. |
