Well, both verbs ехать and идти are motion verbs ( глагол движение ) they both mean to go in English, but ехать is by vehicle and идти is just to go, not specified. ( even though it's used sometimes as go walking ).
The accent is not right in еду, because if you say едУ it's food and Еду is going.
Робот потешный, выговаривает не по-русски, а по-корявому... бедные иностранцы. Я толи иду, толи еду в Москву:D
В/НА (location) = use Prepositional case.
В Москве = IN Moscow
В/НА (direction) = use Accusative case.
В Москву = TO Moscow
