Thank you, this works. But I wish use minimum LUA for this. I recommend to modify current command module (vehicle is located on track/contact). Currently this module uses boolean. Please, add a programmable number: "vehicle is located on track/contact > number" where number is zero by default. Thank you in advance!

I can use proper commands but events are missing. Brake light must be on when curent speed > target speed. But which event to trigger this? On and off. Rückfahrlicht, index lights also. Also I wish vehicle volume adjust to speed. I can use timer but it is massive vaste of resources. Alternate method: maybe recommend developers of vehicles to develop this functions too, like day or night automation.

I think so: portal is not a container. But it can hang up vehicle before pass it to other side. I think not to activate move command before delay.

In case of computing "any vehicle" condition please always exclude current vehicle. It only affects conditions but actions and iterations remain unchanged. Maybe rename condition name to "any other wehicle". Thank you, in advance!

I wish a delay on this devices. I think it is minor change only: portal can not contain vehicles but has a delay before places it to the other side. No need to reduce speed, simply hang up vehicle instead. Maybe one plus thing: in simulation mode portal makes invisible current (entering) vehicle or reduce size to zero, so next vehicle or trailer can enter and does not occupy roads. --- Vehicle automatic acceleration is more realistic with delay (driver reaction time). Random numbers are also acceptable on both cases. Thank you in advance! p.s: sorry my poor English and no Deutsch.
