A method, system and computer program product provide assessing environmental conditions outside an autonomous vehicle and recommending modifications for the autonomous vehicle based on a condition. A plurality of possible routes are determined for an autonomous vehicle using a navigational system. Environmental conditions are assessed, and one or more environmental conditions are identified outside the autonomous vehicle related to each of the plurality of possible routes. A determination is made as to when the one or more environmental conditions necessitate a modification of the autonomous vehicle for traveling the respective possible route. One of the possible routes are selected based on a criteria which includes avoiding a greatest number of the environmental conditions which necessitate the modification. The autonomous vehicle is routed along the selected route to a service station for implementing the modification based on the condition related to the selected route.
