    His book is good, as is his Honda S600/1000.

    Can you mix and match different batteries to best suit available space?

    No, you'll get really weird behaviour if some of the cells drop voltage faster than others.

    Are Tesla motors the way to go?

    Tesla components are an obvious choice, but they're not cheap cars and demand is high.

    Leaf's powertrain is limited to protect its battery, since it doesn't have liquid cooling, the cells are quite easy to repackage, easier to fit in a car than the Model 3's four subpacks for example. Ampera batteries were massively overbuilt for what the car needed, capable of really high output, but supply is getting rarer and a bit old.

    I think your next step needs to be working out the sizes and shape of the spaces left over when you remove the engine, exhaust, propshaft and fuel tank. Also, capture some CAN logs so you can work out what messages you need to keep the Subaru's dash and body-computer happy.

    Do you need the Forester to be 4WD? The 4WD builds I've seen are either using both front and rear Tesla drive units, or they're retaining the original transferbox/centrediff. If you can make do with front or rear drive only, you'll free up a whole load of space for battery.

    This just happened, luckily after a team meeting, and now the back of this IKEA Snille chair is much springier than it should be. Date code moulded into the plastic says October 2008, so not a bad innings.

    I'm glad the 2 lap bollocks happened, solely to reward Russell's P2 in quali. 100% worth it.

    Also, Williams double points finish two races in a row. Chances of at least one car in the points at Zandvoort? Apparently it's Monaco with wind and banked corners.

    the roots of Pritti Patels racism may lie in her parents connections with Idi Amin expelling Asian people from Uganda.

    Her parents were economic migrants who came here years before those who had no choice.

    You won't land anything on a rat, then when you're tired and have given up, that's when it'll creep up and get you.

    Ended up fitting the BB93 temporarily and ordering 4x ZTTO BBs from their AliExpress store, for about £7 each, £33 inc delivery. The ZTTO BSA30 BB I've been using on my fatbike has been fine. £25 and a long wait isn't particularly competitive with uk-online pricing.

    GF noticed some movement through the pedals on her fatbike during its last ride. Turned out it wasn't a loosening driveside RaceFace crank (had that before years ago on similar RF cranks), rather the Hollowtech 2 BB had developed play in at least one of its bearings.

    I used to be able to get Shimano BB51 or similar for £10-15, especially on eBay with people not realising the new cranks they'd bought came with a BB until weeks after purchase. Now I'm only seeing £40+ or out of stock.

    Short of waiting a month for some off-brand anodised AliExpress BBs, is there anywhere selling HT2 BBs at a reasonable price? Currently contemplating a used BB93 that has one smooth side and one slightly gritty side.

    I watched the film The Darwin Awards last week, starring David Arquette. A jet strapped into a car was one of the plot points.
