    The regulatory authorities in Oz would need to get their shit together if electric motorbikes/mopeds/things are to get off the ground in any volume.

    We need something similar to the scooter rules in many countries o/s (Europe, SE Asia). Below XX power, YY mass & ZZ speed, and you can ride it at a younger age on metro / urban roads and not freeways sort of thing.

    Of course this won't happen, as we continue to push the 'zero road deaths' mantra.

    You have no negative feeling about the growing road toll like what is happening in Qld?

    In the same way hire bikes won't take off with dopey rules and manky helmets.

    Saw a doco on the rise and fall of O bikes, lots of shady shit, but the takeout was the helmet laws in Aus are a major hurdle, not many countries have mandatory laws. How are the Beam thingies going up your way Ron? Last time there was quite a few lying around but there seemed to be plans to rectify that, good thing for zipping around the city, we used them a fair bit. I'd buy a couple of electric scooters tomorrow if it wasn't for the dumbarse state regs, so instead we use a stinking great truck to go get shopping and eat at a pub.

    Still seeing them abandoned everywhere, Paul.

    The Greens Minister is trying to salvage the hire bikes debacle by suggesting the helmet laws could be relaxed in the inner areas but that hasn't been introduced yet - maybe just a thought balloon.

    I'm guessing that has nothing to do with young people on bikes, and everything to do with bogans in badly lifted 4wds, crack-heads, car theft, and general lack of old-school policing on the roads.

    EDITED:
    https://www.publications.qld.gov.au...resource/a5f24a26-f29b-4963-97ab-4d67a95836a5

    Couple of points at a glance:
    1. shows no increase per head of population.
    2. extra fatalities are due to drink driving, fatigue, 21-24yo's, unlicensed driver/riders,
    3. Zero moped deaths for 2020. Generally 1-2 per year
    4. old road users (not drivers) - more pedestrian and cyclist accidents?

    Can't open anything on that link :dunno

    As for helmets, watching supposed adults tearing round Civic after dark with toddlers standing in front of them grimly gripping whatever they can to stay on as the "adult" in charge breaks everybroad rule in the book at flat-chat, yeah, I support helmets

    This seems to be about the top spec electric bike available at the mo. Proper brakes, trick engine, etc.

    From the team that make the E bike for MotoGP.

    Call me callous bastard, but I think Darwin's Law of natural selection applies there.

    Came across this today , sorta explains the procedurewhen a EV fire occurs . Pretty lengthy involved process , i can't help but think the enviromentally friendly benefits of Ev are well out weighed by this type of negative .

    Learned something new today!
    Where a 'regular' #car fire is a matter of extinguishing and towing, a fire in a #hybrid car is a much more complicated job. That was confirmed again yesterday when we were called for #smokedevelopment in a hybrid vehicle in #Leuven.
    Arrived at the scene we found a strong smoke development, which pointed to the battery's thermal runaway '. This creates when the temperature of a battery cell rises considerably. Soon after arrival there were already flames visible. After knocking down the flames, we have refrigerated the vehicle abundantly and placed it in a special #waterdipping container.
    After all, a battery that is damaged can catch fire again even after abundant cooling due to a chemical reaction in the battery. To stop this reaction it is necessary to cool the battery for a long time. For this we therefore use a special container in which the vehicle can be immersed for an extended period of time.
    The container was placed in a remote parking lot. As soon as the vehicle has completely cooled down, a branch service will remove it from the container and transport it towards scrap dealer. Not for the sake of immersion, but because a car like this is completely destroyed when the battery catches on fire anyway.
    There was also some attention for the extinguishing water. After all, it was contaminated and we couldn't just let it run away. It was collected in underground rainwater tanks and will be checked before processing.

    Electric scooter rentals were a huge hit in Canberra

    Until the CV19 debacle

    In the window where everything was pretty much back to normal, public servants were zipping all over the place on those scooters - clever app that helps you locate them, and tells you how much charge they have - really easy ...

    Feel really sorry for the two companies that had launched the scooters - must have been gutted by the current lockdowns / working from home - hopefully they can start up again when this is resolved ....

    I teach a 3 hour course titled "Practical EV Firefighting" in the US and your "feeling" is misplaced. For a start, there are less fires involving all EVs and hybrids than ICE vehicles. The data would be much more offset when you take out the hybrids, because their fires are predominantly the gas engine. #Prius
    By memory it seems to me the ratio is 1:143 EVs (may've been just Teslas) are lost due to fire and this includes both arson (oddly not uncommon for Tesla) and vehicles caught in a garage/structure fire. Roughly half of EV fires are sitting unattended, whether on or off a charger.

    On the technical side and for any firefighters here, the difference is in getting firefighters to observe what is burning in the vehicle to know which fuel to address. Plastic, battery, or gasoline in a hybrid. Not knowing this is why so many EV fires are so hard to put out even with 10,000-20,000 gallons of water, when FF who've had a little training can do the job with less than a single 500 gallon engine.

    An ICE or hybrid vehicle burns the gasoline off pretty quickly so the FF is really fighting a plastic fire, as up to 40% of new cars are plastic. Trying to stand back the same safe distance to use lots of water won't work on an EV with the battery involved because the car body is like a boat hull. Water in the passenger compartment spills out the doors without getting to the battery below the floor pan. Rather than just fighting the plastic fire on top with a solid stream, FF need to use spray to cool the battery from the bottom & put water directly into any visible breaches. Breaches will be where the fire is the brightest and strongest.

    The Emergency Response Guides from the car makers generally start with the idea "Consider letting the car burn itself out" then get more aggressive.The "dunk tanks" are used in the EU where the cities are more congested and they want to stop the smoke ASAP because it's hard to evacuate an area.

    Google NFPA EV ERG for links to car maker FF instructions. Any FF should keep this link on their phone and continually think - Which fuel am I trying to put out?
