Interestingly, when I turn the game screen upside down, it reminds me of another game whose speed mechanics could use some improvement - perhaps using your method. That would be fantastic! :-)
If you read the original instructions, it's not such a bad game - for example, the programmers built fuel consumption and refueling services into the game. At first glance, it looks like a very weak game, but it's very detailed on the inside. The main problem is the poor speed mechanics - the ZX Spectrum version of the game was much faster, and people liked this game much better on that platform.
