Explorer top speed slower on smooth surface

[joe_schmoe_gamer]

The explorer top speed is significantly lower on steel or concrete foundations then it is on open ground. Driving along a sandy beach I get well over 100 km/hr. On a concrete road bed I get just above 95. Wheel hop is noticeable.

This is a known bug caused by odd interactions between the vehicle physics and the collision boxes of adjacent foundations.

No news on a fix, but the devs have said on stream that they will likely do "a pass on vehicles" before the game leaves early access

that's why I let my trucks run on the terrain.

For all this high tech transporter\replicator gear, the car and tractor is sure slow, and take grades poorly. Would be nice if there was a MPH toggle also. No Idea how fast I'm going, other then I know KPH is slower to start with, so I guess extra slow speed.

Its a problem both for Tractors and Explorers, because their collision model so far cannot interact with foundations as continuous surfaces, rather than as individual objects. For Tractors its not only causes slowdown but also kicks them off course. It's less of a problem for automated navigation, seemingly because that mode manages simpler interactions, and Trucks are affected less because of their 6-wheel grip and stronger suspension.

Thus you really should only use Trucks for over-foundation transport, and keep Tractors and an Explorers off-road where possible.

Doesn't need to be ultra precise for a ballpark, so Multiply by 1.6 for mph->kmh, and multiply by 0.62 for kmh->mph, Do 0.6 and you'll be close enough.

So a drop from 100kmh to 95 is approximately from 62 to 59mph.

To the OP As already covered by vectorspace, the reduction in speed is due to the vehicle colliding with adjacent foundations- Your 'smooth' surface is not actually smooth due to that bug.

And of course there's a whole other problem with foundations; you can literally see between them. These sorts of small nuances will get ironed out in the final stages, no doubt.

I think it's funny my tractors are glitching/ ghosting everywhere and at the same time deliver a lot :)

I did at one time slip between foundations while on foot. Don't know if I caught a 4-way intersection just right or what, but it happened. So far it's only been the one time, in Update 5.

Actually the reason why automated mod (without pioneer in the vehicle) works better is because the vehicle engine "transports" and despawns the vehicle en route when out of view, so the foundation issue is less burdensome.
The whole problem stems from the vehicle dynamics they use for suspension on ground. The wheels are sunk just below the ground a bit for some reason. On ground that works fine, on foundations they bump the snappoints and edges. Its annoying and immersion breaking. Its been acknowledge by the devs and they suggested they may have to switch the vehicle engine, which is a major pita at this point. So in TBD state.
